I have an old BYTECC hard drive enclosure. Trying to use it on an older XP system for back up. Got a bunch of 40G hard drives I can use.
The OS will detect the external drive is connected and powered up, arrow shows in the tray for a USB drive, checked the device manager and it sezs the drive is there and operating properly, recognizes it, but does not assign a drive letter.
AIDA32 sezs it is there but same deal shows no drive letter.
I've tried four different hard drives with the same results. I know the hardware works on other computers, this particular computer USB works with other canned external drives, it reads a flash memory stick as a drive no problem. I know the BYTECC is set up properly, should be the same as with other computers. Works ok on a Win2000 system.
What could be the problem? Is there something to tweak?
I do know this XP system would not read hard drives that had been formatted on non-XP computers before. Don't exactly know what systems all these drives were formatted on. Isn't making any sense to me at the moment. Doing it just like I did on the Win2000 system with other drives, everything worked as it should.
Thinking I could try to slap one of the drives in as a slave and try to format it that way, hopefully can get it to be read as a USB drive instead.
Any help greatly appreciated.
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.)
If the drive shows up in Disk Management (Start/Run/diskmgmt.msc/OK), right-click the drive icon or the area showing the drive below, select "Change drive letter and paths". In the next window click "Add". Next window click the radio button for "Assign the following drive letter". Select a drive letter. Click OK.
I recently bought a Lacie 1TB external harddrive to store some of the data on my old PC (Win XP, SP2, I cant seem to udate to SP3 because windows update wont work).
The drive is working fine as I've used it on my laptop running Win Vista (64 bit). However, the drive is not being displayed in windows explorer. When I go to My Computer>Manage>Disk Management, I can see the drive there saying it's online, but there's no name attached to it and when I right-click, all the options are grey (otherwise I could of just changed the letter through there).
Using diskpart on command prompt, I still couldn't change the letter. I also found out that there is no volume assigned to this disk.
Can someone please help me?? I'd be forever greatful
I didn't see where you formatted the hard drive. Before you can use any hard drive, external or internal, you have to format it at some point. For hard drives with Windows installed on them, they are usually formatted during Windows setup. For external storage drives, you can format it through Disk Management.
I have a Toshiba laptop (Pent IV, 512 RAM, 60 GB HD) running XP Home SP2. I recently purchase a Maxtor 200GB HD and an external USB enclosure. After installing the drive in the enclosure and plugging in the USB it looks like it is recognized (says Maxtor drive recognized, driver is installed, new hardware ready to use), but it is not assigned a letter when I click on "my computer" so I can't do anything with it.
After reading an earlier thread, I attempted to format the drive by: clicking on My Computer, clicked "manage", and "disk management". In the main window of this screen only my C: drive is listed. In the drop down list below the main window are listed: disk 0 - C:, and then under that disc 1 - unallocated 189.93GB, then under that my CD/DVD. If I right click on dick 1 I do not get an option to format - only "properties" and "help". In "properties" under the "general" tab it says "Device is working properly".
How can I format this drive and get a drive letter assigned to it?
Thanks for your help!

I am running Windows 7 Pro. Have a external dual dock connected to a estata port. One of the drives assigned letter K often comes up as E and I have to change as application is looking for K. Another disk in this dock works fine. No problems.
Does anyone know why this might be happening or anyway to prevent?
Seems like when I go to disk management and assign K it should stay that way.

Try assigning a drive letter a "distance" away from your existing drive letters.
For example, change the dock drive letter to Z and see how you get on with that.
I recently installed a new WD 160Gb drive. I partitioned, formated (NTFS) and installed Windows XP SP3 (using the Windows XP setup program). However, the system has reversed my CD drive and the HD letters.
It gave the HD "E" and the CD drive "C". (It should be the other way around) I can not change the HD letter back to "C". It says I can't change the boot volume letter assignment.
I set the boot sequence in the bios to boot from the CD first, the way it should be for installing a OS, right?
What did I do wrong? Why did it assign my CD drive "C" and my HD to "E"?
Hello. Correct boot sequence, not sure why the letters are reversed - you might be able to (carefully!) correct them, article here seems to explain it fairly well? http://www.petri.co.il/change_system_drive_letter_in_windows_xp.htm

the ext. drive anymore. The ext. drive shows up fine on another pc w/ xp
pro. What .dll or file is missing or has been corrupted to cause this? I
also have a client that is experiencing the similar problem with his new pc
w/xp pro and a USB thumb drive, and thought these 2 issues may be similar in

I recently formatted my 1TB Seagate External HDD to FAT32 to backup and redo my PS3. I reformatted it on my Windows 8 laptop easy peasy, but my windows 7 desktop will not recognize it as a drive with a letter to access it. If I uninstall the drive in device manager it will reinstall, be recognized as a general drive and in that small instance it is accessible, but then it gets fully installed and is recognized as BUP Slim BK. It doesn't see any info for the drive or even know that there is a valid partition on it.
Any help to get this drive working again is much appreciated.
If THIS is your drive and Seagate software governs it...I'd say that the software for the drive may need to be installed/reinstalled.
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?

My USB disc comes up with the letter 'J'. Because I have references to it with a letter 'X'. I want to change it and I do that in the Computer Management tool with the Disk Management utility.
Computer - Right click - Computer Management
Disk Manegement - Right-click the drive and then click Change Drive Letter and Paths
Assigne a new letter
Everything works fine but suddenly after a reboot Windows 8 loses the letter 'X' for this disc and assignes 'J' again.
I have done so with this drive for years under Windows 7 without any problems. Any idea, please what the problem might be?
Hello Senki, and welcome to Eight Forums.
While you have the USB drive connected, double check using OPTION TWO in the tutorial below to see if "J" is still listed. If so, change it to use "X" instead.

I have two hard drives in my computer which is a old Compaq Presario 5WV271 5000 series, both hard drives have Windows XP pro (service pack 3)that I installed on it years ago. It has the max alotted memory, a 10/100 PCI NIC, 900 MHz AMD Athlon Processor, a master hard drive 40 GB (drive C) that I am using to connect here and a slave hard drive 60 GB that says drive D when I am using it but not found when on drive C. For some reason drive C shows a (New Volume F). I am posting here to see if anyone can help me to understand why my slave drive which started out being New Volume F (which it still is when I look for it from drive C) is showing local disk D when I am using the slave. Does anyone have any idea why the slave would reletter itself and how do I correct this?
I will try .
Drive letters are normally assigned by Windows...in the order in which a drive is detected...with one exception. The optical drive is obviously the first drive detected when installing Windows from CD...but it always will receive the D: letter, assuming that there are only two drives (hard drive and an optical drive) attached to the system and, therefore, recognized as existing.
These rules do not apply to any OEM system where a manufacturer has installed Windows and possibly also created either hidden or additional partitions.
Sooo...when I install XP, I have one hard drive connected...with nothing on it...and an optical drive. The optical drive is set up as D: and the partition I create and install XP upon...is set up as C:.
I have no card readers or external drives or USB drives attached, since these can interfere with the hardware recognition process.
Once XP is installed, I open it and decide to create additional partitions on my very large hard drive. I create a storage partition of 100GB and Windows assigns the letter E:. I create an additional storage partition of 150GB and Windows assigns the letter F:.
I then decide to install another version of Windows...on the same hard drive. I use my install CD to create the partition and install Windows and it assigns the letter G: to that install...because C:, D:, E:, F: are already accounted for and in use.
I now have a dual-boot, if I have done everything smartly. One version of Windows as the first... Read more
I turned the computer on today and one of the external hard drives has changed from 'K' to 'L'. Two other external hard drives have not been affected. For some reason the 'K' drive has been allocated to the CD Drive (which was previously 'F').
So how can I get 'K' back to the external hard drive using the same path as before. It doesn't matter what the CD drive is called but getting it back to 'F' would be nice.

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.
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.
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"

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.
STEP 3: WINDOWS SERVICE PACKS
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.

In the limited research I have done with the problem posed in post #56, I believe the reason the user is unable to use the drive is it is GPT and is protected. Is there a way to reclaim the drive and data in Windows 7?
I am unfamiliar with GPT and do not know how to get Windows 7 to give access to the drive without changing to MBR, but changing to MBR will wipe the partition table and make the data inaccessible. Any ideas? Anyone else seen this problem before?
I stumbled across a forum post (TomsHardware) that claimed TestDisk and PhotoRec have the ability to recover data from GPT drives. Is it worth a go?

A few days ago, I installed a game on my external hard drive. At the time, the hard drive was assigned the "F:" directory. They other day, I plugged a video camera into my computer before the external hard drive making the camera "F:" and the hard drive "G:".
The game won't work while the hard drive is assigned to "G:". I've removed the camera, there are no other USB devices plugged in (except my mouse which doesn't have any storage capacity) but still when I plug in the hard drive, it goes back to "G:".
I've tried plugging it into different sockets, logging off the computer, restarting the computer, but still, it goes back to "G:".
Why is this happening and how can I get it back to "F:"?
Never mind, I've got it working.
We typically use "F" as the root drive letter for our network access. One of our new Win 7 (64bit) machines has assigned F to a CD drive that does not exist. The two DVD drives are M & N. When you open My Computer it shows F as a CD ROM drive
but the drive does not show up in the Disk Manager. I've been into the Registry and F is not linked to a DOS device. I"m not sure where to go now.
oh? try plugging in a card there and see. maybe then you'll be able to select a different drive letter for it in Disk Management.
or just unplug the scanner, unload its driver, and see if the phantom drive F: goes away.
I have a Seagate Barracuda 7200 500 GB SATA drive that worked fine in a Windows XP computer that belongs to my elderly Dad.
Then one day after the machine sat for a few months it would not power up. I suspected the power supply but before I had a chance to look at it, my dad took it to some small shop repair place he found in the yellow pages and they told him the MB AND the HDD was bad because “it was old.” I think they were just trying to sell a new computer to my Dad.
I was suspicious so, not having a compatale power supply to replace the old one with, I took the drive out placed it into an know good external case and plugged it into my Windows 7 laptop as an external to see if could get the data off.
The Drive spins up
Shows up in Device Manager with no errors
Shows up in Disk Manager as a Disk1 Healthy Primary partition but I cannot assign a drive letter (option grayed out). The only option availalbe is Delete Partition.
UPDATE: Drive DOES show up as DISK1 in Diskpart LIST DISK.
Drive does NOT show up in Computer
Is there another way to assign a drive letter so it will show in Computer and I can get the data off?
What would happen if I make it a Virtual Drive?
Or, is the drive really bad?
Hello, and Welcome,
It could be a bad enclosure. When you used Diskpart you used the list disk command, correct?
See if taking ownership of the drive lets you change the letter. The video is for Vista but the same applies to Windows 7.
Other option: Burn a Puppy Linux iso to a CD. Boot Puppy. On the Puppy desktop you will see your hard drives listed. Attach the external drive. You will see a USB icon appear next to the DVD icon. It will most likely be called sdb1. If there is more than one partition on the external they will be labeled sdb1...sdb2 depending on the number of partitions. Click once on the sdb partition. The disk will automatically mount and you should see the files on the hard drive.
Your Windows 7 partition would probably be sda2. Click once on it and if you do not see your Windows files close out the file manager and try another partition. You can highlight the files/folders on the XP disk using Ctrl+ left clicking or by windowing around the files/folders. Drag the highlighted folders to the Windows 7 file manager window. A small dialog window will appear. Click copy and quiet. You only need to click once on a folder in Puppy to open it.
I'm trying to assign a drive letter to my sata drive via the computer management utility.
The drive is listed but when I right click the only option available is delete partition.
I want to assign a drive letter so that I can access this drive to hopefully repair a problem I'm having with a corrupt system file that I have listed in another forum.

I purchased an external USB2 hard drive case (that has a power cable and USB output cable) and installed a 120GB Seagate drive. It seems like my laptop (running XP, USB1) will recognize the drive when I plug it in (as an USB Mass Storage device) but it does not give it a drive letter (like E) for me to access it. I have tried changing the Master, Slave, Cable Select jumper on the drive with no success. When I plug in a USB thumb drive, my laptop assigns a drive letter and I can access it via Windows Explorer with no problems, but with the 120 GB external drive, I have no luck? The drive shows up under the Control Panel.....Device Manager as a hard drive just under my laptop drive, but there is no way to store files on this external drive. Any suggestions?
Hello and welcome... You may need to configure the drive in winXP for it to be seen properly.

However when I right-click on the drive, the option to assign a drive letter is grayed out.

Can anyone help solve this problem.
I have two hard drives installed on my PC, and run Win 98 SE. As Windows had been playing up a little I re-installed Win 98 se to try and solve the problems.
Unfortunately Windows now only recognises the C Drive. Both hard drives show in the BIOS, and in System in the control panel. It just doesnít seem to allocate it a drive letter. My CD ROM and CD writer drives still have the same drive letters as before.
I have not changed any hardware, so itís not jumpers/cables etc. The drive has not been re-formatted. I tried doing FDISK from the DOS prompt, and that only showed details of the C drive.
Any ideas ?
Try an FDISK /STATUS.
When you fire up FDISK and check details, it only shows you the first disk drive, you have to use selection 5 [change disk] to look at other physical drives.

I bought a new SATA Western Digital HD yesterday (WD3200JD/7200R/8M) as an additional HD. I already have a WD 160G drive running as the master. I've attached the new HD to my motherboard (Gigabyte GA-8I915D Pro), but it is not being recognized or being assigned a drive letter. I can see it in the Device Manager, and the report says it's operating properly, but no dice. Belarc shows it as Drive 1 (although the Device Manager lists its location as "0 (0)" - the same as the master), but does not list in local drives.

I've been digging around forums for hours but can't find anything useful among all the hardware/driver issues.
I have a 2003 server (completely updated) that will not automatically assign a drive letter to any external storage device that is plugged into the USB ports. I've verified that this happens with every external storage device I've been able to get my hands on - several flash drives and many external hard drives.
When any device is plugged in, the drive is detected and shows up in Disk Management but I have to manually assign it a drive letter, typically the next available drive letter.
Once the drive letter is assigned it works fine.
If I unplug the device, give it time to remove, and plug it back in, it is once again detected but no drive letter is assigned.
I get the same effect no matter what drive letter is assigned, whether it's the next available or something out in left field like W:
As stated above, I've tried every different device I can get my hands on.
I've made sure all available updates have been applied to the OS
I removed and reinstalled the USB Controller drivers
I even removed the USB controller card and installed a different model with a different chipset
I'm at wit's end here
Are you sure that it doesn't show up in "computer". Any usb storage device I have ever used always shows an an external device.
My problem is unlike the ones listed where the drive can't be used. My ACP-EP 512M flash drive worked fine on my W2K pro machine, until the hard disk fried, and and I put in a new disk with Win XP pro. Then the flash drive worked OK for a while (2 weeks?), and now:
- the machine doesn't give it a drive letter when inserted in any USB port (I have 6 or so)
- it shows in the task bar for removing it "Safely remove USB mass storage device"
- Disk management doesn't list it
- it works fine on all other machines, 98 SE, several W2K pro, Mac.
(It sounds like HW with the computer now with XP Pro, except that it worked fine with 2KPro and XPPro at first, and it works with other USB devices.)
Have you tried any other USB device with the system in question? Or have you tried all six with your flash drive?
Possibly a port issue
As backup drives, computer uses external Maxstor 1TB using a firewire and a WD 500GB using a USB. The maxstor is assigned drive "K"; the WD is assigned drive "L". Periodically, the system fails to recognize drive "K." I.e., I look in my computer and it has vanished. If I unplug the maxstor and then plug it back in, the system assigns it to drive "M." If I go to computer management to reassign "M" to "K," "K" does not appear as an option. In other words, "K" has been locked by the system but appears to be unuseable.
(1) What would be the reasons the system keeps dropping "K?" The system never drops the WD that uses the USB.
(2) The only way I have found to reassign "K" to the Maxstor is to reboot the computer and then "K" appears under computer management. Is there a less painful way to get the Maxstor back to "K?"
I am not very computer savvy so would appreciate answer in do this, do that rather than answers such as "check bios" which is meaningless to me.

After the migration I faced a strange problem which when I dug deeper I realised that the any drive/partition that I assign the letter D will never show up in This PC as a connected drive to access, although this D drive is visible in Disk Management and appears as a visible drive. However, I can access the drive when I type D: in the address bar of explorer. I infer, with my extremely basic understanding and knowledge, that my system is for some reason set up to hide drive D, regardless of what it represents, hidden in This PC. I have tried everyting from formatting the D partition, to hiding it and then unhiding. Nothing works. I request the community to please help me solve this problem. CheersAlfiRead other answers
I recently purchased a new computer to which I transfered my existing Windows XP install (copied the partition with Partition Magic then did a recovery off the Windows XP disk because it wouldn't boot). I am now having a strange problem with my USB flash drive. I plug it in, it is detected as normal, but it is not assigned a drive letter. I can go into disk management and assign it an unused drive letter but it still does not appear in My Computer or Windows Explorer.
If, while still in disk management I right-click the drive and choose "Explore" Windows Explorer pops up showing the drive contents for just an instant then automatically refreshes to My Computer... which still does not show the drive letter! I've tried refreshing the view, going to run and typing the drive letter, all to no avail. Rebooting the machine changes nothing. And my Firewire iPod has the same problem.
Any suggestions would be greatly appreciated!

The letter, F, is already assigned on all workstations to a resource on the server; however, Windows assigns a new USB thumb drive the same letter, which results in an inaccessible USB drive.
I changed the USB drive letter in Disk Management to I. This holds until the USB drive is disconnected and the computer is restarted. Then Windows again assigns the letter, F, to both the network resource and the USB drive.
How do I make Windows hold the settings I give it?
And, why would it assign the same letter to two resources, anyway?

I have a situation that isn't really a major problem, but is slightly annoying, and somewhat puzzling.
I have an external 1TB Iomega USB hard drive on my system. It is set to be Drive Y. Most of the time, everything is fine. But occasionally, after I boot the system, I'll get the pop up on the screen asking me what I want to do with Drive J. And yes, the "new" Drive J is, indeed, really my Iomega external drive. I can go into Disk Management, and reassign the drive letter back to Y, and everything is fine again.
Sometimes, it keeps the Y drive letter for several months at a time. But other times, the system treats it as a new drive and assigns drive letter J to it--in anywhere from a few days to several months after the previous time.
As I said, it doesn't happen often enough to be a problem, but I'm curious as to what causes it. Anyone have any insights into this little puzzle?
Look in your registry under HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices. That's where drive letter assignments are stored. Find \DosDevices\Y: on the left side and note the data value on the right. The next time it happens, check the same registry location but find \DosDevices\J: and see if the data value is the same as before. Also see if there's still an entry for \DosDevices\Y:.
I have a new 120 gig external USB drive (105G free). It installed and seems to work fine except:
My prior system had hard drives C: and D:
cd reader drive E:
DVD/cd RW drive F:
four-way card reader G:, H:, I:, J: (these came and went depending if card reader was left plugged to the PC)
The new external installed correctly as drive K: and I succesfully backed up a zilllion photos.
After shutting down/startup the drive assignments redefine as
C: and E: Hard drives
D: as new external 105 GIG free
F: as CD reader
G: as DVD/CDR
H: as a second identical new external 105 GIG free (duplicates drive D
The four way card reader is unplugged-ran out of USP plugs.
I have two problems:
1. The duplicate external drive assignment is obviously wrong but I cannot make it go away.
2. I cannot make a backup program work correctly since the drive assignment keeps changing.
How can I "lock in" the hard drive and CD assignments so the external drive doesn't jump in the middle of that alphabet. I want the External drive to always be assigned some higher alpha letter so I can use it on different computers.

Hi all, newbie here. Thanks for any advice and direction re: posting.
All I want to do is see what's on the old drive, specifically find out whether or not it has XP installed before I install it back into the tower it came from (a Compaq that has other problems not worth fixing if this IDE drive isn't bootable). If it has XP, fine - but it was set to slave.
I've connected the IDE drive, a Western Digital Protege (40GB), to my Win7 HP Pavilion Slimline via an Ultra "USB 2.0 to IDE/SATA cable adapter" with the jumper set to master as directed. I've tried plugging the drive in to both the front USB port and a back one. The drive spins up fine. I tried to boot from it on my HP and it won't do it.
No matter where the USB cable is plugged in, the Protege is recognized by BIOS, appears to be shown in the Registry but with multiple entries/weird prefixes, and shows up in Disk Management as Disk 1 but without a drive letter. I can't assign a drive letter to it in DM - the only option not greyed out is Delete Volume:
In elevated command prompt, the disk does not show up via the "list volume" command.
So. I think I read somewhere (been searching for an answer for 3 hours now) that you can't change the drive letter when it contains an OS. Is this true? Is there a way for me to assign a drive letter/examine the files on this IDE drive?
In my experience, when you're connecting a single drive this way, you generally do not have any jumpers set. You could try it that way to see if it makes any difference.
And no, it doesn't matter if any partitions on the drive contain an OS. I do this stuff all the time for the same reasons -- reusing an older drive that has an OS installed on it. I've not had problems assigning drive letters to the partitions on the drives.
I'm getting around to getting my new Lenovo Notebook set up prior to replacing the stock HDD with a Sammy 840 EVO and I'm having a couple of problems that have me stumped.
1. The first time I plug in an external drive, be it HDD or flash drive, via a USB port, I have to go into disk management to assign a drive letter to it even though it already has one and was working fine when I would plug it into my desktop machine. Once I assigned the drive letter, it would work fine from then on except for problem #2.
2. Once the drive has a drive letter reassigned, I have to go into Computer to find it since the little window with the Autoplay context menu doesn't appear. I've checked the Autoplay settings and have everything set to ask every time (the way I prefer it). What am I missing here?
Edit: Ok, this just got weirder. I just now tried plugging in the external HDD into the preferred USB 3.0 port and the little Autoplay window decided to pop up like a good little window should. After ejecting and disconnecting the drive, I then tried rebooting the computer, then plugging in the drive. The little window popped right up. Same for the flash drive I had trouble with before when I plugged it in. I then tried plugging the external drive in again and had to go into disk management yet again to reassign the stupid drive letter again. Yeeesh!

I have Toshiba Satellite, in case that matters. I have drive C, D, E of course. I also have 2 external hard drives. G is for movies only. F is for backup. Anyway, yesterday I noticed that the letter F wasn't showing when I clicked on Computer. I went into Disk Management and tried to assign a letter but I saw 3 G letters. One was fine but the other two confused me. I tried to change each one but the letter F was missing. In frustration I deleted that drive. Well, now I can't get it back. What do I do? BTW, I see the two externals in Device Manager and I think I see one in MiniTool Partition but the drive in question is marked as Unallocated.
Can you help me? All my important backups are on there.
Check this article.
first, I have searched a lot on the net and seen that this has happened to a lot of other people. In my case, it is System Reserved (G, and is using 71.9mb of 99.9mb space.
Other users are discussing removing it, merging it with (C and so on. But my question is - can I just leave it as it is, with no ill effects? I'm not bothered by it, as long as nothing has\will go wrong.
thanks for any answers,
I have this also. It is not an issue for me and I don't see why it would cause ill effects. Cheers.
My laptop is a Dell Latitude D830 running Windows Vista.
I've bought a Freecom USB 2.0 Hard Drive XS 1TB (Model Code SSYBBA) which came FAT32 preformatted. I wanted to reformat to use NTFS so I plugged it in to my USB port. Opening Windows Explorer, the drive was picked up as G:\ and I could view files on there and copy and remove files so I knew the disk was working OK.
I started reformatting by right-clicking on the drive letter and selecting "Format" from the menu and select NTFS and kept the default settings. After an hour I cancelled the formatting (clicked Cancel) and a message popped up asking me to confirm, so I did.
Since doing this, the drive is now no longer recognised and doesn't get a drive letter assigned. I've tried rebooting, reconnecting and checking in Disk Management and it just doesn't appear (although is powering up when the laptop starts). Also, Device Manager doesn't show it. Screen shot of Disk Management attached.
Can you tell me, how do I get the drive letter back to restart reformatting?
Thanks in advance for your help.
What options do you have when you right click on the drive?
I'm in a bit of a pickle here. I have my suspicions what the problem is and I hope I'm not right.
Recently my computer died. I pulled my hard drives and DVD drives and stuffed them in another box. I turned it on and it repeatedly restarted after a blue screen of death. The blue screen went by so fast I couldn't read it. Soooo, I reinstalled Windows XP Pro and SP3. After doing so, my second HD is not being assigned a drive letter. Device Manager sees it, Disk Manager sees it and says it's healthy, active and NTFS. Is there anything in the Registry I can change to make it accessible? (ALL of my music and personal documents are on this drive and I can't afford to lose ANY of it.) Or do I have to format it for the OS to recognize it as a drive? Please help soon.
Right click My Computer, click management, then enter the "Disk management application on the left.
Right click the drive that has no letter, click "Change drive letter and paths, Click add, choose an unused drive letter, click OK, and you're set.
I have a PC running Vista Ultimate x64 and I just installed a 1Tb external hard disk (an eSATA/USB 2.0 combo) Through USB.
The problem is that the OS doesn't assign any drive letter to the external disk.
I tried to reinstall but it doesn't work at all.
In Disk management, choosing to "initialize" the disk, I selected the MBR partitioning style...but it returns an "invalid function" error message.
How can I fix this problem?
The system reads that there is a disk but it doesnt' recognize it and it doesnt assign any drive letter.
Did you format it ? ?
Many drives ship unformatted...
TIP: If you want it to keep the same drive letter even when USB devices are added ( handy for all sorts of reasons ) once it's formatted select a drive letter that's not currently in use and assign it....next give it a Volume name.
This also works with thumb drives as well...
