Drive letter problem installing Win XP Pro x64 & Intel RAID

Q: Drive letter problem installing Win XP Pro x64 & Intel RAID


I'm attempting to do another clean install of Win XP Pro x64 on an Intel DX58SO motherboard in RAID 5 with four SATA 500GB Seagate Barracuda drives. The problem I have is that windows defaults to the drive letter "I" for the RAID. I would like it to be "C" drive. I've attempted to change the drive letter after the install, but the system won't allow drive letter changes to the system disk. Is there a solution to this issue? Thank you in advance for your assistance.

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

A: Drive letter problem installing Win XP Pro x64 & Intel RAID

What type of RAID are you installing 0, 1, 5 etc? Are you doing a Striped set, MIrror etc? Make sure you have no other external drives (USB, SD, Flash etc) installed at the time, Other then the CD/DVD drives, At the partition information window during the install, it will tell you what drive letter it is going to install to.

Hi there
Yesterday my computer was shut down when I returned home.  I may have lost power but I am connected to a UPS that should have kept me safe from any surges.  Turning the computer on, my RAID5 drive (drive letter M) is gone and a mysterious new drive
has appeared, labeled as drive E, also showing as a RAW drive. In disk management, I can see that drive M is its normal size, 11177.94GB.  I am using 4x4TB drives.  Intel Rapid Storage Technologhe shows all four
drives as healthy and functional.  Drive E shows in Disk Management the same as Drive M, and I have no idea how it ended up there and what I should do with it.  My C drive shows up and works normally, where I have my OS and programs installed.
Not sure where to start, but hoping it is just an issue with the MBR?

I am running 7 pro 64bit on a ASUS p8p67 deluxe mobo and I copied all data from my 1tb storage D: drive to a backup external and proceded to install raid 5 with 3 single 1tb drives and the raid is up an running. However using Intel Rapid Storage Technology to setup the raid inside windows I had to use the drive letter R: because D: was not available in the list option. When I start some programs, the program is looking for the data on D: drive. Is there any way to change the letter of my raid storage from R: to D:?


A:RAID 5 switched from single storage to raid 5, lost drive letter

It's possible the cd-rom/dvd drive assigned itself as d: before the new raid was created.
This should be solvable using the windows disk management tool if that's the case.

I'd appreciate some help. I'm setting up 2 x Western Digital RE4?s in RAID 1 for Data Storage in a Win 7 Ultimate 64 bit system that is using a single SSD for the OS.

The two RE4?s have been set up in the option ROM and when the OS completes startup, Rapid Storage Technology indicates that the drives were set up correctly in RAID 1.

The drives have been initialized. However, the RAID Volume is not being seen by the OS.
Here?s what I?ve tried: I right-click on ?Computer?, left-click on ?Manage? which takes me into Computer Management. I then left-click on disk management which provides a graphic on the right side of the screen of the unallocated RAID volume. Right-clicking on the unallocated graphic provides the choice of: ?New Simple Volume?, ?New Spanned Volume?, ?New Striped Volume?, ?New Mirrored Volume?, ?Properties?, and ?Help?. Note: ?Change drive letter and path? is NOT available as an option.
From there, I?m not sure how to proceed. The graphical representation of the unallocated volume is the RAID Array. I don?t want to create another RAID 1 Volume.
Any help is appreciated.

Planning on a new build with storage as follows:

1 - 320G SATA drive partitioned for XP + various apps

2 - 320G SATA in RAID 0 for gaming

1 - 500G SATA for b/u

will be using a P5N32-E SLI 680i board and XP Pro.

I am considering a larger #1 drive with a partition in case I decide to try Vista.

I'm confused as to the physical procedure for setting this up. IF I install all the drives in the system and start to configure, will I run into drive letter issues while setting up the RAID? I'm thinking the 1st physical drive w/b C & D, the RAID 0 will be E and the b/u will be F.

I've set up multiple drives before but not with a RAID array involved.

Any help will be appreciated.

My raid 0 drive(s) will not retain their drive letter after reboot. I have to manually set it every time I start the PC.

Initially I "accidentally" set the raid partition to active (overactive clicking while not watching the screen), then thinking it did not really matter just went ahead and set the drive letter to "E" which is the default, and first available entry after a and b. Upon reboot it did it again, lost the drive letter.

I then proceeded to go into the command prompt, and set the drive back to "inactive" which removed the active flag on it. No big deal, easy enough. I reset the drive letter. Then, thinking this might work somehow I rebooted again. Same problem, lost the letter.

I tried a different letter, thinking it could possibly be some registry issue or something, which is very well might be, on the grounds that a different letter might force a new entry? Idk, not all that hot with the registry.

Reboot, same problem.

So now what? I want to back everything up to my primary drives and then reinstall the OS using the raid drives as the system drive. But if this is going to happen again in that case that would be less than ideal.

I have a dual Raid 1 configuration with (2) identical 500GB (C and 1TB (D drives. When connecting my (2) external hard drives, one of which needs to be named (F (I have numerous files, folders, icons and programs linked to it), I see that (E and (F are the only two drive letters unavailable for use - presumably because they have been allocated as the invisible/dynamic? drives for (C and (D, respectively. How do I know which one's RAID Mirror is? And can I just rename that drive so the letter becomes available without interrupting/changing/affecting the RAID configuration? Thanks in advance for anyone that can offer insight.

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

Let me give you a brief summary of my problem.
I recently sent a server (MoBo Intel 955XBK, 2GB Ram and two Western Digital HDD Sata2) for colocation, so I have no physical access to it. I configured everything correctly, and it was working fine before shipping. (By the way, both HDD were in Raid 1 Mirror).
There was some kind of trouble with the case so one of my friends intercepted the server and was forced to remove both HDD from the Motherboard.
I don't want to bore you with details, but the thing is that when the server was finally online, I had lost the array. Now I can see both disks independently and the Intel Matrix Storage software with which I created the arrays is not running because it says that "The driver is not correctly installed".

My question now is, do you know if there's a way to install the driver (usually done pressing F6 when installing Windows) within Windows and build the array from there?

Thanks for you help guys

A:Problem with Sata2 Raid 1 MoBo Intel

The driver was installed originally so it should still be there. Perhaps you can go to the Device Manager to uninstall the SATA controllers, restart and let Windows reinstall the drivers.

By Gigabyte system board uses "Intel Rapid Storage Technology. Version (c) 2003-11 Option-ROM" as a firmware function. This version does not support Win 10. I contacted Gigabyte and they pointed me to version 14 software drivers which do support Win 10. The only instructions that came with the drivers where to put it on a flash drive for Windows to read during the install process.

So I did this, but Win 10 crashed with a:
0xC1900101 - 0X40017failed in the second boot phase with an error during Boot operation.

Based on the three error messages that were given during the failed upgrade attempt, it does seem to be a disk read problem.

My best guess is that the upgrade did not see the drivers. Or maybe software drivers do not trump the firmware drivers. Anyone have any suggestions?

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
up just fine in Computer Management (shown below), but not in Computer. So I think, ok, I'll just add a drive letter but that option is greyed out and won't let me. The disk is initialized and appears to be healthy. I have gone to device manager and made sure
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.

A:Add drive to Raid Array. - Re-installing the software

You may be able to make #6 be a hotspare without worrying about the array but I think if you want a total of 6 drive raid 5 with no hotspare you will have to rebuild it. Don't quote me on it but I am reasonably sure this is the case.

Usually on servers there are 2 ways to access the raid configuration 1) usually there is a raid utility that is loaded after the OS or 2) the other way is on bootup when it initializes the array you can hit some key combination to get into the array at the pre OS level.

When i tried a clean install of windows 7 (Home premium) the installation setup couldn't detect my drive and I tried loading drivers from flash drive manually got the message "No signed drivers found.....".
No options to set SATA mode in BIOS.
Didn't know which driver to load tried all these drivers Intel Management Interface Driver, Intel Chipset Driver, Intel Rapid Storage Management Driver but got the same message.
Help me with the right drivers to install win7 or win8.....

A:Installing Win7 on Raid mode Drive

Where did you get the installer? Use the latest ISO burned to DVD or written to flash stick from Clean Reinstall - Factory OEM Windows 7.

For Home basic you must download Premium ISO, run the eicfg removal tool to unlock all versions, choose Basic from the menu at boot.

If you have an EFI BIOS, you'll need these special steps to install to UEFI (Unified Extensible Firmware Interface) - Install Windows 7 with - Windows 7 Forums
and UEFI Bootable USB Flash Drive - Create in Windows.

Or you can Bypass UEFI to Install WIn7 which always works.

A:I want to setup a hard drive RAID 0 without installing windows on it

for raid, you need drivers. but firstyou need to turn on the raid controller in bios, and then enter the raid configuration utility upon the next reboot where you can set up the array. not all motherboards do it this way, and i'm assuming that you have the raid controller integrated int o the motherboard (not an add-in card). once you get that set up, install the windows drivers. you can then partition and format the volume using disk management.

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?

I am trying to revive the local Priest's computer - he has nothing backed up (and I'm not even Catholic ;-))
He has a Dell Dimension 933r running Windows XP Home. When he started the computer yesterday it started to boot into Windows and then just restarts in an endless cycle. It got to a point where it came up with an error "autochk not found - skipping autochk" and then a Windows XP BSOD (the ones with some hex addresses) pops up with an error for about a tenth of a second (I cannot read anything on it - it is too fast).
I pulled the drive and put it in another computer. The computer (Win XP Pro) finds the drive and it shows as "healthy" in Disk Management, but it does not assign it a drive letter. I would just like to be able to get in and copy his data.
I tried a repair install, but Windows XP says it cannot intall to the partition.
I downloaded Maxtor's PowerMax (it is a Maxtor 40GB drive) utility and the drive passes all tests with no errors or failures.
I can see directories, etc. when I boot in the Windows Recovery Console, I just can't do anything with them. It tells me "access is denied" when I try to go to documents and settings, etc.
I have tried a fixboot, etc.
Anybody have any ideas how I can help him get his data back?

I've just set up a new RAID 1 array with two WD 500GB drives. One of the drives was connected to my previous system and has four partitions on it containing all of my data - the first partition is 20GB, blank and ready for a new XP install.

I used BIOS to setup RAID 1, it took about two hours to mirror onto the other new 500GB disk.

I used my XP disk to setup Windows, pressed F6 and used a floppy to install the SATA RAID drivers - once I'd done this, the XP Setup detected the single RAID array and let me format the 20GB partition and copy all of the setup files. So far so good.

But when the computer reboots for the first time, I get the error message "Invalid partition table" and nothing else happens. It's got me stumped.

If I leave the two new disks in and boot XP from my old 80GB hard drive, Windows loads fine but the RAID array doesn't work properly - I get two copies of all my partitions with different drive letters.

Any ideas people?

Ok, my system now as is:

E: 2x75gig RAID striped 0 with mostly games etc. on it

I am trying to arrange the system so that the RAID drives are C: and run windows. I dont have a problem re-installing most of the other programs so that they have the correct path names etc.

I tried installing XP on the RAID drives, push F6 and loaded the raid drivers, it found the partition, and proceded to copy the files. On reboot, however it crashes, saying something about windows\system32\ is corrupt and to run the repair console. I've done that a few times to no avail. I was even curious about the install CD so I installed it to D: and had no problems booting up there.

Anyone have any Ideas? I know I could probably reformat and clean install, but I'd rather not go through all of that. Thanks for any input.

A:Problem installing XP on RAID drives

Set your boot order in BIOS to CD forst then scsi (for RAID), when the files have been copied setup must boot to the new installation, if you dont have SCSI as the second active bootable device and 'any other' is set to enable it will boot to C:\ and cause no end of problems, ideally you should detach the drive already containing an OS unless you specifically want a dual boot system.

You can't change the drive letter of the drive/partition that Windows is installed too. Windows won't let you do it. That drive letter is referenced by a lot of programs when they are installed and changing it would cause a lot of programs to not function correctly.

A:Can't change hard drive letter to needed letter

Hello Stevie,

To be safe, you should create a restore point before doing this in case you make a mistake and need to use it to do a system restore.


1. If the K letter is not being used by another internal drive, then you can open regedit and navigate to:HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices
2. In the left pane, Take ownership (step 2 in Option Two of METHOD TWO) of the registry key MountedDevices and "Allow" yourself "Full Control" of it as well.

3. In the right pane of MountedDevices, right click on \DosDevices\K: and click on Delete and OK.

4. Restart the computer to apply. You should now be able to change the second hard drive letter to K.

Hope this helps,

The problem is that the Memors Stick reader does not show up in Disk Management as long as it is empty - and I haven't got any Memory Stick. How can I re-assign the card reader's drive letter although there is no Memory Stick inserted?

If the card reader has 2 drivers you may be able to disable the unused one.

Please go to start>search>type device manager.
Are there any "unknown devices" with yellow triangles on them?
Is you driver there , listed, and working?

If not why does it matter what drive letter a partition has?

 Hi, I have a Samsung SSD PM841 om my Dell Latitude E6430, i7 3.0Ghz, 16GB DDR3, Win 7 Pro, 64-bit, laptop. I have a 250 GB powered external HD attached to it. In 'My Computer' there is no drive letter for it. When I click on SSD c: then properties,
then hardware, it is shown in that drive, (like it's a partition of that c: drive). Also, d: is my 'recovery', a partition on c: drive. I want to move some of my files onto my external HD, but I cannot do it. When I highlight a file, then click on 'send to',
there is no drive letter for my external HD. Seems like my computer is making the external HD part of c: drive only, not a drive on its own. I have never had a problem hooking up external HD's before, but I very new to SSD's and I'm at a standstill on how
to fix this problem. I've tried what others have said, in windowsforum/windows_7, but with no results. I believe there's a simple solution for my problem, can anyone help me?...Thanks, Forrest

A:Drive Letter Changing Problem

If you are using XP Pro then you can modify the drive letter assignments. It's "Computer Management" under Administrative Tools. Inside that is "Disc Management". If you're using XP Home, then I am not sure how to do that.

I have a computer which has the boot drive set as letter F and not C. I can't install a certain program which I really need. I think I found a method so that I can change the drive letter, but I'm afraid it will completely mess up my computer. The method is found here: http://support.microsoft.com/kb/223188
Please let me know if this is the method I should use and in what way it should be executed. Thank you.

A:Solved: Boot Drive Letter Problem

Read other 7 answers

I have a system here that occasionally will change the drive letter of the external drive. So far, I haven't been able to detect what triggers this change.

System is an HP Media Center PC with built-in card reader and two DVD drives. Drive letters are as follows:
C drive for OS
D drive is the system recovery drive
E & F drives are DVD drives
G, H, I & J are the card-reader drives
K is the external USB drive used for backup and some other purposes.

Occasionally, I'll come to the machine to see why the K drive isn't accessible across the network and I will find the following:
C drive for the OS (same)
D drive for system recovery (same)
E & F are DVDs (same)
H, I, J and K are card-reader slots (changed from G, H, I & J)
L is the external USB drive used for backup (changed from K)

Is there a way to lock in these drive letters to stop these occasional changes?

Okay, here's my problem. I have 2 hard drives in my system: C, which has Windows XP on it and D, which contains data only (mp3s, videos, images and so on). I have reformatted my C drive today and reinstalled XP on it, BUT for some whacky reason this drive has changed to D and what use to be D has now become C but it doesn't have any boot or system on it. So when I try to boot my system I get an error message (sorry don't recall what it is exactly), I can only manage to boot using the Win XP CD.

So now I'm trying to switch back the drive letters, but I'm not sure if it's doable. I tried (by going in the administrative tools) but Win XP doesn't allow it. Is there any way to make things right again? Or do I need to reformat everything again...?

Thanks for any help!

I've just come across an odd problem. There's a soulution on MicroSofts suport site on how to change the main drive letter back to C:\ should it have changed somehow.

Following instructions everything went according to plan up until the reboot. The main drive is now C:\, but everytime i log in it logs straight back out again without even getting to the desktop.

Has anyone else had this problem and overcome it? If you have, i'd greatly appreciate any tips you could give me. Data loss is not an option unfortunantly. *Sigh*

Thanks in advance

A:Problem after boot drive letter change

I do not know what it was before you changed it but everything in Windows was set to that drive letter and when you changed it to C:\ Windows can no longer find anything because everything is set to the old drive letter. The one thing you should not change is the boot drive designation.

You may not even be able to get to safe mode now, and that is a bummer. We will work on getting your data safe and backed up.

First thing you are going to need is another computer and it has to have a burner in it, doesnot matter if it is CD-R or DVD but preferably DVD burner.

You are going to have to remove this hard drive from this computer and install in the other computer as a slave drive and when it is able to be accessed by Windows you will have to backup all of your data manually and then burn to a CD-R's or DVD.

When all of the data is backed up you then re-install the hard drive into the first computer where it came from as a master drive on the primary IDE cable and then format the drive and totally re-install Windows. Use this document and print it for reference if needed

I seem to have a problem with my external USB drive.

I needed to change the letter of one partition from H: to E: and it wasn't a problem.

To my doom, I had a usb dongle plugged in that had the E: letter assigned to it. The drive letter changed but left the partition unreadable (winXP wants to format it and Ubuntu says that the partition is not NTFS anymore).

Any ideas please?

A:Multiple Physical drives as one letter (No RAID)

I am not sure if this is possible as I am having hdd troubles myself and it seems that I have 2 hdd's the same letter which is confusing the computer. I would think that this is why raid was "invented". Like I say, not sure but Im am sure that someone with more knowledge will come along and correct me

For Trim to work in RAID 0 Intel states with the latest IRST Drivers they provide, also provide by Lenovo, an up-to-date Intel RAID ROM or EFI RAID "SataDriver" from v11 up needs to be present within the BIOS. My questions is does my Lenovo P70 with the latest 2.03 BIOS, have this Intel RAID ROM or EFI RAID "SataDriver" from v11 up ? I would really like to know if Trim is working since I run RAID 0. If not I would request Lenovo update the BIOS so folks like me who run RAID 0 get Trim enabled.
