Cannot get Storage Spaces to retire a damaged drive - Array remains invisible (no drive letter)

Q: Cannot get Storage Spaces to retire a damaged drive - Array remains invisible (no drive letter)

I've posted on the problem I'm having with my Storage Space (set to file 2-way duplication) before. I know I'm going to lose some files. I removed one drive to reformat it to a larger clustersize and, while the array was repairing itself, I lost
a 1TB drive that will no longer connect.

I've "Removed" the drive and gotten the error "Can't remove the drive from the pool" because "...not all the data could be reallocated. Add an additional drive.."

I already can't re-add the old 4TB drive (even though I've done nothing to it) because Storage Spaces says it's now an "unrecognized configuration". At least a disk recovery tool can find files on it (though they're all named nnnnnn.JPG or nnnnnn.AVI
or nnnnnn.DOC)

However, my 15TB array (X:\) can't be seen because it thinks it's lost two drives - fair enough - and even though I know I'm going to lose some files (the most important of which were backed up in File History) it refuses to allow me to remove the faulty 1TB
drive. I added a new disk and it STILL won't let me.

How can I get my X: drive back? All of the disks in the array are 40-60% full - there's PLENTY of space to duplicate the files that ARE down to one copy! What can I do?

(As per a suggestion in my other thread, I tried a System Restore to before the point where I'd Removed the 4TB drive and that didn't help since I couldn't select the X: drive to restore!)

I believe I lost my boot drive. My computer hangs when it can't find SATA4 in BIOS. I tried switching cables, but it did not help. I have 4 drives in a storage spaces array and a single boot drive. The computer is older, so I am thinking about pulling the 4 drive array and putting it in a mediasonic 4 bay box. I would attach it via usb to a windows 8 laptop. I only use the array for media storage.

Will the laptop see the array correctly in the usb box?

A:Boot Drive Failure with storage spaces array

So I went ahead and bought the mediasonic 4 bay box. I put in the 4 drives from the array and they showed up without any problems on my windows 8 laptop. They are linked by USB, but still show up as a regular hard drive.

I created a Storage pool with the following setup. Three 3TB drives with parity all in an external enclosure with eSata and USB 2/3 ports. It was connected via USB when created and had production data loaded and tested without any issues.
After a few days of use I decided to see what happened when I tried to access it via the eSata port. No luck, due to a driver on the eSata card issue with Win 8. So I powered all back down and plugged back in via USB. At this point the Storage pool went
into the state as per the screenshot below. Any suggestions to either fix the issue and/or retrieve the data that is in the volume?

Hi everyone. I'm having issues adding an additional drive to an existing Storage Space on my new Windows 8 setup. Its an external usb 3.0 hard drive, 2 tb western digital My Passport.
Ok, so anytime I go into Storage Spaces to add the drive to the pool, it gives me an error:
Can't prepare drives
Close all applications that are accessing the drive, and then try again.

The system cannot find the drive specified (0x0000000F)
I've searched everywhere and tried just about everything for a solution, but there isnt much out there in regard to this. =/
I also noticed that the drives details are always blank, however it shows up fine in My Computer as well as in my Computer Management setup.

Thanks in advance for any help you can give!

Storage Spaces/Drive Pool makes independently checking each of the data hard-drives impossible? Quick-read via Google has me believing the software needed to view data folders & files resided on the now-defunct OS hard-drive, is that correct? And, there was no way to make a WinPE-like Storage Spaces/Drive Pool & Macrium Reflect usb boot stick or DVD boot, correct? Or, was there a way originally and such boot was not made?

When adding an initial drive to a storage pool I get the error "incorrect function"
System: Proliant ML110 G4, Windows 8 64-Bit, 4GB Ram
I have a 160GB drive installed on the motherboard's controller which hosts the OS
I've installed a single 2TB drive on a 2 Port PCI Express Internal SATA II Controller Card (JMB36x).
As soon as I create a pool using the 2TB drive I get the error "Incorrect Function" and the drive becomes RAW.
The drive id's are unique.
It's worth pointing out that the system without the new controller can only support 2TB max of SATA drives, but this is bypassed by the controller card I added?
Help is appreciated.

Hm, this is the reverse of a problem that happened a few days ago, that guy found a solution that may relate to this - I'll try to find him and have him take a look at this thread. brb! Welcome to Windows 8 Forums btw.

OK I sent the guy a link to this post, hopefully he can give you something to try. I'm not familiar with using Storage Spaces that much, there are a few in here who are.

I am setting up a new home PC\Server and decided to use Win 8.1 since I needed to upgrade to at least Win 7 Professional to use Disk Mirroring. Now I find out Win 8.1 has Disk Mirroring (From Disk Management Console) and Storage Spaces.

My question is which one is better and faster. I just want to mirror two drives (RAID 1) to store my pictures so if one drive fails I have a copy. I'm not interested in expanding this or adding drives that Storage Spaces seems to support.


A:Win 8.1 Drive Mirroring VS Storage Spaces-which is better

Basically, if you just want to stick with mirroring, just stay with RAID 1. You can also do Storage Spaces and set it up to basically act like RAID 1, but I can't tell you if one is faster or not. I'd imagine both are the same, that is of course unless you have a RAID card with a dedicated processor.

Something happened to one of the drives on my storage spaces pool. I can no longer see the files, so I tried to remove the storage space. This operation fails with the error: "The disk structure is corrupted an unreadable". There are also similar NTFS errors in the event log.

Type storage spaces in the Search box, look for a panel that says "Select drives to create a storage pool", there may be a place on that one to Take offline.

Hi, and thanks in advance for any help!

The general situation: I have a Windows 8.1 Pro machine acting as a home server. The storage spaces volume (singular) consists of a 4-disk array with 2TB drives in Parity mode. It's usage is 70ish% but honestly, maybe 50GB is important to
recover, the rest are ISO's which I have the physical disks to so no big deal if I lose those. The volume is in a bad place and I need to either get it functional again or get the data off of it and start with a fresh volume.
What seems to be wrong: One of the drives has failed. When the drive is attached the volume (D:) appears to mount but explorer hangs/crashes when attempting to access D:\. Storage spaces hangs/crashes as soon as you click "Change Settings".
Task Manager registers 100% I/O usage of the volume at those times. Taking the drive to another machine and running CrystalDiskInfo indicates a few fatal failures. Removal of the drive returns the system to a functional state but D:\ goes away.

Attempts to fix the issue so far: With the drive attached the storage pool will say 'repairing' and sit at 0% for at least 3 hours (at which point I gave up). All further attempts I've made have been w
ith the bad drive physically removed. Removal of the drive via the GUI shows this error
Can't Remove Drive from the pool
Details: Drive could not be removed because not all data could be reallocated. Add an additional drive to this pool and reattempt this operation

I've searched but not found an direct answer. Pls excuse if I have missed something.

I'm running a Storage Spaces on a Win 8.1 machine with a few partitions. I just discovered that my large partition couldn't be enlarged over 16TB due to my 4kb cluster size so I created a new, smaller, partition on the drive capacity that I had left with
64kb cluster size. Fine so far. I then started moving files to the new partition thinking that I could somehow reclaim the unused space from the old, large, partition and then "transfer" it to my new, smaller partition. But now I'm stuck as I can't
find a way to reclaim this unused space. Help!
I've tried running the "Defragment and Optimize Drives" tool but no change.

Windows 8:

I have 4 drives assigned to a raid1 and a raid0 storage space. A power plug broke off of one of the drives. I ordered an exact replacement hdd pcb for that drive. It spins up, bios sees it, I'm 100% sure no damage was done to the data as the drive was off when the power plug was broken. windows sees it but storage spaces thinks it is a new drive. So spaces is still showing the raid0 offline and raid1 in lowered resiliency mode. I am assuming something on the logic board, maybe hdd serial# or guid or something is now different for the repaired drive.

Does anyone know in powershell if there is a way to tell storage spaces that the repaired drive is in fact the one that it thinks is offline?

Hello everyone,

I have a windows 8 machine that acts as a media storage computer on my home network. It has 8 storage drives varying in size from 1 to 4 TB. I have been using Drive Bender to create pools, however am interested in switching to Storage Spaces.

Currently with Drive Bender I have created several pools for storage of different media (movies, TV shows, Audio, Photos). Each pool has several drives within it. There is no replication of the files within the pools. They are configured as JBOD with 1 mount point.

Since I have no replication of files I need to be able to get files of of a drive if something happens with the program that manages the space. Drive Bender does a good job of this and I never feel like I will lose a file if Drive Bender breaks.

1) Can I get files off of a drive if Storage Spaces "breaks" and how would I do this?

2) Drivepool (not Drive Bender) has several options that allow management of how data is written to the pool of drives (such as filling 1 drive then moving to the next keeping files together). Is this an option with Storage Space?

Thanks for any help you can provide me.

I'm trying to create a storage pool for parity with 4 3TB drives and use 3TB of a 4TB drive that also has my OS.
When I go to create the pool the 4 3TB drives show up but the unallocated space on the 4TB with my OS doesn't show up.

I have done some research and heard that this might be possible but it seems to be a case-by-case situation.

I'm running Windows 10 Home.

I have a 4x 2TB drive storage pool setup with storage spaces under parity mostly used for movies/tv shows. I decided to buy 2 more 4TB drives and add them, but I only have space for 1 more at the moment (only 6 SATA connectors on my MB). After adding it (and appearing successful), it attempted to rebalance but eventually stopped changing the %complete and Storage Spaces eventually crashed. I tried again with my second drive, and the same problem. If I do "get-storagejob" in Powershell, every time i boot up it has 3 jobs (screenshot in linked Imgur album) and 2/3 of them always fail at 42%.
I've tried removing both of the drives that failed to add (crashes), I've tried cancelling the rebalancing (crashes), and many other things but Storage Spaces continues to crash as soon as those 2 jobs reach 42% or I do anything to change something.
Data on the drive appears accessible, but any attempt to view results in eternally spinning progress bars (sometimes a second or two of video before sputtering out). I'm usually pretty good with Google and can solve my own problems but this has had me spinning my wheels for days.

Hi All,

When creating a Storage Spaces Pool, the member drives are no longer listed in Disk Management.

My system has been hanging every so often and when I checked the Windows logs, I see a lot of critical error messages about Harddisk/DR10 having a bad block. Since Disk Management no longer lists the individual pool drives, how do I find out which DR10 is one of the pool member drives?

I've tried mini partition tool to see if it can see the drives, it doesn't. It can only see what Disk Management sees and that's only non-storage spaces pooled drives.

Many thanks!

I had 3x 3TB drives in a parity pool. It started to fill up so i added a fourth 3TB drive and months later one of the original 3 began to fail on me. Performance was slow, then slower, then it showed disconnected.

I retired the drive and added a replacement, literally the same model 3TB drive. I cannot however, get it to remove the failed physical disk and repair the pool. I even tried adding another 2TB drive i had available in case it needed the extra space (didn't make sense but i was reaching).

I get the "drive could not be removed because not all data could be reallocated. add an additional drive to this pool and reattempt this operation."

Any ideas on what i need to do? I have searched a lot and don't really seem to be getting anywhere. The only way i was able to retire the drive was through powershell. I'm assuming it's a GUI issue and perhaps i'm not approaching it correctly via powershell. Attempting to repair virtual disk didn't work.

Any help is appreciated! I really don't want to lose this data. I wasn't able to backup much before the drive failed completely.

I have a USB storage device that insists on being mapped to drive H:. The problem is that drive H: is already mapped to a server. If I boot XP with the storage device attached, I can't get to my server drive. If I insert the USB device after boot up, I can't access it at all.

I recall a means to change the default mapping of hardware drives in prior versions of windows but cannot see how to do this in XP. The other obvious work around of changing the network mapping will not work for me because of corporate policy.

Any ideas for how to re-map the USB device would be appreciated.

Hi All,

My problem is a bit of a strange one although I'm hoping someone can help. I have a 4gb Compact Flash Card housed in a Datel Media Dock (that connects to a Nintendo DS Lite). When I connect this dock to my PC via USB cable (to download movies, mp3's etc) the pc will 'ding' to recognise I have connected it, it will also show in device manager, it even shows in the 'safely remove hardware' icon in the task bar but it cant be seen in Win Explorer. It cannot be seen in Disk Management either. I know that the CF card is good because taken out of the Media Dock it is seen by my media card reader and I can load/unload fine. I know that the cable is good, the card is good, and the Media Dock works fine in my Nintendo DS. This exact same problem happens with my laptop using all the same gear. Its as if the PC can see it but doesnt want me to do anything with it. the manufacturer of the doc (Datel) have been no help. I'm desperate for ideas, anybody got one?

Many Thanks

A:External Storage Device Not Assigned Drive Letter

Read other 7 answers

Hiya, hope someone can help. XP has decided not to assign a drive letter to any flash card reader/USB drive I use in my PC (previously used drives no longer have a drive letter in Explorer)

Going into Computer Management/Disk Management the drives are detected with no drive letter, I can give them a letter and access them but the letter doesn't stick, nor is it seen in Explorer (ie remove drive and replug, no letter, no auto open options and no sign of it in Explorer)

I've tried going into regedit, mounted devices and deleting all letters (apart from A-floppy, C-Main HD, D-Optical drive obviously) to try to force XP to assign a letter.

I don't want to do a system restore (all drives worked before) as I've just managed to instal SP3 RC2 after a lot of hassle plus I suspect this has nothing to do with my new/odd USB drive problem.

All other USB peripherals work perfectly, tis just Mass Storage Devices won't display, I tried a new drive and XP went through the New hardware bit, recognised it, said it was ready but didn't assign it a letter/ open it.

Any ideas how I can force Explorer to open the drives ? (going through Admin Tools is a pain after all)

I run Win XP Home SP2 on a Acer laptop. I have a number of USB storage devices - a digital music player which has a 40GB HDD which shows as a removable USB drive in Windows, several flash drives, an external full size HDD (250GB, Western digital).

My laptop has 1 internal HDD partitioned to C: and D: The DVD-RW is E:

Recently when I plugged in my music player to transfer some songs, it wasn't recognised in Windows Explorer/My Computer. The green "safe removal" icon appeared in the system tray, but no drive icon in Explorer.

I checked Administrative Tools / Computer Management / Disk Management and the drive appeared there with the correct next available lette (F: ) It said "healthy" but when I right-clicked to try and open it I got the error message "This operation has been cancelled due to restrictions in effect on this computer".

I have got around the problem by assigning another drive letter, but I have also found that other devices that are assigned F: (as the first "free" letter) by the system when plugged into the USB port (like another USB key) don't work in a similar way, until I manually reassign them a different letter.

What is wrong with F: ?? Is there anything I can do to let it work?

Or do I just need to use the other letters and thank my lucky stars there is a way round it!!

A:Solved: F: drive letter not working (suddenly) for removable storage

OK a long time after the original post, but ... better late than never:

There is a registry key that had been created called NoViewOn Drive in HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer

It restricts access to drives based on the binary value (1=A: drive, 4=C:, 32=F: etc)

I deleted this key , rebooted and now it works!

I have a drive that has a lot of information on it that I need. A user left our company and all of his files are on this drive. I was handed it and asked to build a VM with all his information on it. When I plug the drive in it loads the drivers and shows

there were no problems there as well. It was also an external drive so I removed it and made it an internal drive on my machine but got the same results. It shows up in BIOS but obviously can't boot off of it since it is not an OS drive.
Deleting/formatting the drive is not an option. Is there a way to get this drive accessible without that? Deleting it is the exact opposite of what I want done here.

Apologies if this has already been covered. I did try a search but got nothing specific to my problem.

I currently have 4 Windows 8.1 Pro units around my desk.
One is general day to day.
One is gaming, audio & video work.
One is a currently retired 'server' for backups.
One is the replacement 'server' for backups.
This contains an SSD system disk, a 2Tb HDD for Macrium Reflect images and 2 Storage Space pools.
One consists of 2x250Gb HDD's called DATA & assigned to drive letter 'D'.
The other consists of 4x1TB HDD's called STORAGE & assigned to drive letter 'E'

The replacement 'server' unfortunately decided to go do-lally :(
All I know is, it suddenly decided to reboot 4 days ago and everything went haywire.

As a result I purchased a new motherboard, CPU, ram with the intention of building a fresh install of windows 8.1 on the basis the storage pools would show up in the new system.

Here is the problem !
The pools show up in Control panel /Storage Spaces as DATA (F:) and STORAGE (G:)
Both pools show as OK and all 6 drives show as OK.
If I click on 'view files' nothing happens :(
If I go to windows explorer they show up as Local Disk (F:) and Local Disk (G:)and if I double click to open I get a 'Location is not available. F:\ is not accessible. The volume repair was not successful'. Same for G:

Why is Storage Space manager saying they are working properly when nothing else can access them?
Are they recoverable somehow or have I lost everything ?

First thing you're going to do is fill in the specs of the desktop whose snips you are showing us.

Then you're going to do the same with the second pc opening a second post with snips. Give it a different title like "Second pc with drive letters the same". Don't forget the snips.

You should not have dynamic disks in either machine. What did you do to accomplish this?

There exists a bevy of spectacular experts on this site that will be happy to help you. But give us ALL the info please.

I was building a new array, using drives formatted with larger cluster sizes to get over the 15.8TB drive limit.
Since you can't 'remove' a drive in the GUI and have everything rebalance, I physically removed the drive while powered down.  Upon rebooting, Storage Spaces said there was a missing drive and I clicked "Remove" so that the repair work would
start (plenty of room since I'd just moved 7TB of data to the new array).

Then disaster hit.  One of my 1TB drives failed hours into the Repair process.
It appears the drive has failed - powers up, spins up but no computer can see it and it doesn't show up in the Disk Management tool.  I may have lost irreplaceable pictures and home movies.  I'd be using mirroring for just this reason.
HOWEVER - the 4TB drive I removed?  Haven't written a thing to it or used it in any way.  When I spin it back up, I get that Disk 14 is Healthy with "Storage Spaces Protected Partition".  Is there ANY way I can "re-attach"
this disk to the array to make up for whatever was on the 50% of the 1TB drive that was mirrored on the 4TB drive?  Only files who were on those two disks and no others would be affected and those are the ones I'm worried about.
Thanks in advance.

I want to prepare a factory fresh drive so that I can use it to save backup images. Soon I will have a second drive that will only be used to store data files. Neither drive will ever be used for the installation of an operating system. From what I've read, I see no advantage to having more than a single partition on either drive. I know I want to use NTFS.

This should be straightforward. I'm finding it is not. I cannot formulate a search that points me to the right tutorial or thread. Either I get hundreds of options to consider or, if I try to narrow the options, no answer is found.

Please point me to the right discussion. Perhaps the answer will help others who come after me, too.



A:Format & Partition New Drive to Use as a Backup Drive or Storage Drive

Do you know how to make a partition and format a drive?

You can do it all in Windows Disk Management.

You don't need to do anything special to the drive just because it is going to store images.
Treat it like any other drive.

Format it with a single partition.

Store your image files on it. Use a folder structure if you want to---perhaps naming a folder something like "Macrium image of C partition, 060714" so you know the date of the image.

Nor do you need to use a separate drive just for image storage.

Make your images and store them like ordinary data. Back up the images just like you'd back up any other important data file. That's what they are: important data.

A:Reading a file without spaces into a 2d array

If you will edit your text and put [ code ] at the beginning of your code and [ /code ] at the end of your code without the spaces in between the brackets. It will format the section of code for everyone and make it much easier to read.

I'm not a C++ guy, I'm actually a Java guy. But I'll play around with it and see what I can figure out although, some of these TSG folks can probably help you out before I figure it out.

I just bought a new P50. Bought a Crucial mx300 M.2 SATA SSD drive to install, bought the mounting kit and everything. Read over all the documentation including the hardware maintenance manual.  Installed the drive LABEL UP, with 6 pins on the left and 5 on the right. Turned on the laptop, instant electrical burning smell, SSD error. Turned off the laptop and found this.. There is also damage to the bay and the board.  NOW... I tried putting this drive in flipped over and went with the LABEL UP standard. I could not find ANY INFORMATION ON WHICH WAY TO INSTALL THE DRIVE... there is NOTHING about m.2 drives being asymmetrical.. no information anywhere for the p50 in regards to this. Not to mention you cannot even see the bay as you install it. Lenovo is currently refusing to cover damages by my warranty (I also purchased an extended warranty) Crucial sent me a new drive and is looking into it.  I'm waiting to hear from a repair technician, but basically customer service (who literally knew nothing about computers btw ) told me that it would not be covered because it wasn't a Lenovo drive.  Anyways, just wanted to vent and warn you all. I still can't find a definitive answer on which way to install it, or even if it was installed improperly. Lenovo simply called and told me it wouldn't be covered and they literally just said what I wrote down on the piece of paper.. they didn't even do a diagnostic or anything.. &... Read more

Has anyone tried the new Storage Spaces feature in Windows 8? Your experience with it?

More specifically:

1. If this system is used on a shared network with other operating systems such as XP and Windows 7, can the storage pool drives be set up as shared, and become visible and usable from the XP and Win 7 machines?

2. If you have a Network Backup drive, like WD My Book Live, will it see and back up the Storage Spaces configured drive just like any other drive on the network?

A:Storage Spaces (Storage Pool) Experience?

I've only set this up on a Windows Server 2012 configuration therefore I cannot provide the exact steps on how to set one up in a client environment. That being said, a storage space/pool is essentially a virtual disk that resides on one or multiple physical disks allowing you to accumulate free space. For example if I have multiple servers with free space on their data drives I can then create a storage pool to accumulate this. To allocate this storage pool/space to a user or machine you will need to decide what you wish to do with it. Below are a couple of examples of how:

Share via Windows Folder Sharing (UNC Path)Use iSCSI to use the current ethernet infastructure allowing you to assign the storage pool/space a drive letter to the client machineIn a server environment you may wish to use it for DFS (Distributed File System) to maintain redundancy

Personally I use my storage pool as an iSCSI drive for which i have partitioned.

You can only use the free space of a non Windows install drive. To my knowledge you cannot overcome this with partitioning.

In relation to your second question, you will only able to use the share as a safepoint backup if it is shared via Windows Folder Sharing. For example: \\computername\share

Also you will need to make sure that the NAS is on the same workgroup as the Windows 8 machine hosting the storage pool otherwise it will not be able to find the share. Hopefully this is what you asking however pleas... Read more

I have a USB external hard drive that I keep all my documents etc on (had it for years)

I upgraded from Vista Home to & Home Premium then had to upgrade recently to Professional to run my Sage. Through all these upgrades my ext. drive ran fine. Occasionally the drvie letter would change if I had something else plugged into the USB, this was always easily corected in disk management by changing the drive path.

The connection on the case packed up so I had to get the drive put into a new case, now when I plug it in the drive is assigned G instead of F, I tried to change the drive letter allocation in Disk Management but it won't let me as the program still thinks I have a second ext. hard drive which is labelled F. I suspect this has happened because when the usb connection broke the drive was disconnected suddenly instead of a proper eject.

How do I get Disk Management to remove the inactive drive - i can't find any obvious way - eject, delete etc are all missing when I click on tools or tasks.

If there is no easy way then how do I stop program updates for Adobe etc. failing because they can not find the F drive. I don't know why they look at that drive anyway.


A:External Hard Drive - Drive Letter changed - unable to change back


Welcome aboard.

Try this:

Download drivecleanup.zip V 0.8.1 from

Drive Tools for Windows

Unzip to a folder. In it you will have two folders Win32 and x64, each containing DriveCleanup.exe for Windows 32bit and 64 bit respectively.

Now unplug all the USB devices from your PC (except of course the Keyboard and mouse), right click on the appropriate DriveCleanup.exe for your system and run it as an administrator.

This will remove all non-present drives from the registry.

Reboot and then plug-in your external drive.

The drive will be installed and hopefully you should be able to assign any free drive letter to it.

Please report whether it resolved your problem.

Have just installed a new 8.7 Maxtor in a P100. This drive is set as master and partitioned into 5 which assigns drive letters c,d,e,f,g . If I re-install the old 500mb drive unit as a slave ( Quantum Maverick) it assigns itself as drive letter D. I want this drive to show up as drive H . If I go to Device manager, hard drives, double click on generic ide type 47, settings, for this drive the drive letter assignment is there, but I cannot change it. Any ideas please.

A:{SOLVED} Slave drive letter inserts itself within master partition drive letters

I don't think you can change it. Normally the bios will take the primary of the 1st ide drive as c, the primary of the second ide as d, the next partition of the primary ide drive as e, etc.

A:maxtor external hard drive unformatted and undesignated by drive letter

What size is the hard drive?

Do you know what motherboard you have?

STEP 1: CHECK POWER (click for expanded instructions further down the page)

Verify that the drive light and the light on the AC adapter (power supply) is illuminated normally.
It is sometimes necessary to contact Technical Support for troubleshooting and/or possibly to replace the power supply if it behaves unusually.

STEP 2: CHECK CABLING (click for expanded instructions further down the page)

Confirm that your USB/Firewire cable is firmly connected in a port that is on the rear of your desktop computer (if you have a desktop).
Try another USB or Firewire port.
If your drive is powered only by USB, such as the FreeAgent Go, the Maxtor OneTouch mini, and the Seagate Portable drive, then the drive's cable has two USB connectors. Try connecting both of the free USB connectors into a USB port for maximum power availability.
Avoid connecting the drive via a USB hub for now.


Follow these instructions to ensure that your installation of Windows XP/2000 has been updated to the latest Windows Service Pack.

Right-click on My Computer and choose Properties.

The System Properties window will appear. On the General tab (which will be at the front), see the "System:" information.

For Windows 2000: Update to Service Pack 4.

For Windows XP: Update to Service Pack 2.

Allow your computer to complete the installation ... Read more

I'm playing with a recently retired server running 32bit Windows 7 Professional. Originally it was configured as RAID 0 with 5 SATA drives. Those drives are gone but I want to install a spare 2TB SATA drive that I have. Using the RAID Management software I have created the drive and it shows the correct configured capacity. I initialized the disk with Disk Management and it lists the disk as online but it doesn't show up in the volume list with a drive letter. My intention is to use the 2TB drive as media storage. Other than combing RAID and Windows 7, what am I doing wrong? Am I better off reformatting everything and reloading Windows?

A:Unable to assign drive letter to newly installed SATA drive.

I had the same problem this week with a drive like that. Have you tried to reformat it? Also make sure your system can handle a 2TB drive.

I'm booting off my SSD which is drive C:\ and I have games and programs on an extra hard drive which was origanally drive H:\ but after a restart it switched to I:\ and when I go into Disk Management to change it Drive H:\ isn't there.

A:Hard drive isnt allowed to change the correct drive letter

Hi KiityCancer,

What you say makes perfect sense. So, if a restart changed the drive letter to I, then H won't be there. Why not just leave it at I or is there more to this story...

Hi,Bit of background first, my old harddrive , which was split into  C and D ,approx. 500 gig each, went Kaput,had it replaced with an SSD(at my request because I heard they don't overheat and are faster) by an experienced computer technician, and no longer  having to deal with split drives suited me fine.I only  have half the storage space now, about 500Gg in comparison to 1,000 Gg,  but cost was a factor at the time, SSD's being so expensive.Very happy with the new SSD, speed etc. My operating system is Windows 7 Home Premium 64 bit , SP1. My backups were all stored on a Goflex external harddrive, which  the technician accidentally  dropped on the floor, he then replaced this with an external drive with an on/off switch. (Pleased about the on/off switch, the other didn't have one, very upset about the dropping my other one). All working fine, doing my backups to my new external drive  he gave me, using  my Acronis True Image software 2015 version, that I had always used.My old external  drive was set up to drive E, and all my previous backups in Acronis show drive E, so perhaps this is why the technician set this new one up to Drive F, not sure.And maybe this is why I got the error message below? Well, in my infinite wisdom (which with computer technology isn't great I must admit) I suddenly decided I wanted to backup to an external drive with the letter E,(E for External seemed so much mor...

A:Changes to Drive letter & rename causing backup problems to external drive

 I don't use Acronis, but if you think changing the drive letter caused a problem, can't you just change it back?  The Administrative Tools applet of the Control Panel is what I've always used to change drive letters. Changing the name (I assume you mean the drive label) should have no effect.
 Good luck.

My External Hard Drive (My Book) was always Drive letter F.

I went to sleep and woke up to find Windows 7 Pro had updated and rebooted and I was welcomed by my login screen.

Consequently now my My Book external HDD now reads as Drive letter G.

I went into Administrative Tools > Computer Management > Disk Management

Drive letter F is not available.

F is assigned to a drive that does not exist and never has. I am confused. I only have one CD drive and it says now that I have 2 even though the one addressed as F doesn't have any information. If I click on F it says "Insert Disk"

Got a strange problem that popped up recently.

When I am in windows explorer and my drive letters are in the right side pane of the window...(IE clicking on My Computer in the left pane shows all drive in the right pane..) Instead of opening up that drive's folders, it pops up the search window.

Before I had just clicked on the drive and it expanded out and you could click on the files on that drive.

Anyone know what might cause this to change or what I can do to change it back?

Not a major issue, but it's puzzling as to how it got that way.

Normal Drive letter vs Mounting a volume as an empty folder


I was wondering what the prime uses for a logical drive (just assigning it as the letter F: for example ) might be vs. Mounting the logical drive as an empty folder that supports drive paths?

And why someone would want to use one option vs. the latter? (common uses).

thanks for any ideas.

(I only have one hard drive, so this would be an extended partition on the same disk)

I recently bought a faster 2TB hard drive to replace my old 1TB 'games' hard drive. Unfortunately, the software that came with the drive (Seagate Disc Wizard) will not clone my 'games' hard drive onto the new hard drive. Every time I try the clone, the software tries to reboot the PC, thinking that I'm trying to clone the OS onto the new drive, and I'm not.

Will copying everything from the old drive onto the new drive and then renaming the new drive letter (I to the old 'games' drive letter (E (after removing the original 'games' HDD) work the same?

A:Can't clone a new drive; can copy and rename drive letter work?

When cloning software asks you to reboot it's because they notice that some of the stuff you want to clone is used by Windows somehow. Even if you were just copying files or whatever. Maybe Steam was active or some kind of background program.

Anyway, in case that utility is just dumb, you can try with the program I use all day, EaseUs Partition master. Once installed, just clik on Wizard and then on Clone disk wizard, follow the wizard and you're set. Click on Apply when ready.
In case it asks for a reboot, let it do so (it takes a bit of time for so big drives though, so do it when you have something to watch on TV or whatever). If you selected the right drives in the wizard it won't screw with C, maybe it just needs everything to be sleeping while doing its job.

Will copying everything from the old drive onto the new drive and then renaming the new drive letter (I to the old 'games' drive letter (E (after removing the original 'games' HDD) work the same?

Yes it will work fine. FastCopy is an utility that will help you transfer so much data quickly and efficiently (more than copy-paste), and can check that all files were copied successfully (just to be sure), and stop/begin again the transfer without a lot of fuss.

I have just bought and installed (to the point of completing initialization under Disk Management) a new 1 TB hard drive. Originally, I was planning to use it solely for data storage.

However, I am thinking of installing Windows XP Pro and all the programs I currently use on it, thereby making it the new OS and programs drive, while using the original 120 GB HD as a data/backup drive.

I think the main appeal of doing this, for me, is that it also presents an opportunity to reinstall Windows on a machine which hasn't had this done for more than three years, and which currently seems to take at least five minutes to boot to a "usable" state, despite having a reasonably high spec for its age (it was bought in 2001, but as a result of the upgrade I did in 2006 which led to the last Windows install, it has a 2.4 GHz AMD chip, an Asus A8N-E motherboard, 3 GB of DDR2 RAM, 7600-series PCI-E graphics card).

This has put me in a quandary with regard to whether I should use the new HD as the OS drive, and if I do whether I should partition it and, if I do that, which drive letter(s) I should assign to it.

I don't appear to be able to choose 'C' as the new drive letter under the New Volume Wizard (I can't even choose 'F' since I have an 250 GB external USB backup drive currently assigned as the F: drive). If I choose 'G' (the earliest letter of the alphabet currently available), must it remain hereafter the G: drive, even if I do... Read more

Well, I was lucky. The HD that failed this morning, works if I lay it on its side. So I was able to ghost everything over to the new drive. I ghosted the boot partition c: to r:

I'm using Windows 2000, SP4. The new boot drive is SATA. The old, failing boot drive is IDE.

I worked through a number of problems, but I'm left with this:

When the system boots into the new drive R:, it still wants the boot partition c: for something. If I boot with the IDE disconnected, it'll boot to the login screen, and allow me to log in, but after a few minutes of a blank screen & cursor, it drops back to the login.

I have PartitionMagic 7.0, and used DriveMapper to change all references to C: to R:, but that didn't do it. How do I cut my system's dependence on the failing drive, before it fails altogether? Will this work?

I found the following advice from crjdriver, and was wondering if this would work for my particular problem:

Make a full system backup of the computer and system state.
Log on as an Administrator.
Start Regedt32.exe.
Go to the following registry key:

Click MountedDevices.
On the Security menu, click Permissions.
Verify that Administrators have full control. Change this back when you are finished with these steps.
Quit Regedt32.exe, and then start Regedit.exe.
