Drive letter not assigned but seen for removing

Q: Drive letter not assigned but seen for removing

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.

Any ideas?
(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.)

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.)

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

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 ?

Many thanks


A:No drive letter assigned!


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.

A:New HDD not assigned a drive letter

Hi all,

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 changed the connection position on the motherboard also with no luck.

Any suggestions?

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.

I have 4 USB memory sticks I use on a regular basis, a 4, a 16, a 32 and a 64 GB. This problem only happens with the 64 GB stick, and only on one of my several computers.
Most of the time when I insert it, windows does not automatically assign it a drive letter. I have to into the computer management --> Disk management section and manually assign it a drive letter. Occasionally however when it is inserted, windows assigns it a drive letter just fine. This only happens on one of my laptops. It works fine of all of my other computers and every other computer I have stuck it in. In addition, all the other drives work fine with that laptop. Any idea whats going on?

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

Hi there, I am using a Lenovo Y-50/70 Touch and I recently changed my hardrive from a 1 TB SSHD to a 2 TB SSD. 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. CheersAlfi

Windows XP

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 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.

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!

A:Solved: External HD Not Assigned Drive Letter

Hello everyone,

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!

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'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!

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

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?

Thanks again.

A:Old Western Digital IDE not assigned drive letter but is recognized

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 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"?

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 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 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?

A:Slave hard drive shows different assigned letter on itself than what is on master

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

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.

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?

A:Healthy Drive will not allow Drive Letter to be assigned

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've a Dell pc with a small, hidden diagnostic FAT16 EISA partition.

Starting a few days ago, this formerly hidden partition appears to have become visible to Windows XP which assigns it a drive letter.

I used the command "mountvol /d" to remove such newly created drive letter, but it reappears everytime Windows boots or restarts, even in Safe Mode.

Has anyone experienced anything similar? Is it possible that a certain registry setting relating to the (formerly) hidden partition has somehow been altered? If so, how can this be reversed so that no drive letter is assigned automatically to the (formerly) hidden partition?

An interesting observation is that, in HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices, there is no \DosDevices\{x} (where {x} is the drive letter) which corresponds to the drive letter now assigned to the (formerly) hidden partition.

I cannot use the Disk Management MMC Snap-in to remove the drive letter assignment, since selecting the partition and right-clicking only brings up a single "Help" line in the context menu, without any of the usual options (like "Change Drive Letter and Paths...").

Thanks in advance for any suggestions and feedback!


A:Hidden partition becoming "visible" and assigned drive letter by Windows XP

Read other 7 answers

My windows 7 is suddenly applying a drive letter to the system partition, and removing the letter which causes the "new disk inserted" window to keep popping up every half second. In Disk Manager the drive letter appears and disappears every half second.
The only way I've stopped it is to permanently apply a drive letter, which means it is now visible in windows explorer.

A:System reserved partition becoming "visible" and intermittently assigned drive letter by Windows

I assume by 'system partition' you really mean the hidden system restore partition installed by your PC builder? If so, then after I just fired up Paragon Partition Manager to see what it makes of that partition on my Win 7 PC, I find the partition is Primary, NTFS, active, not hidden, volume name WinRe.

The main interesting thing is the volume letter seems to be set to '*'. It appears as (*) rather than (C: ) as the OS drive does. Furthermore, the main menu has a 'partition' tab, where one of the options is 'assign drive letter', and the next option below is 'remove drive letter' which is currently greyed out.

Looking at the standard Windows computer management, storage, disk management, I see a similar picture, except there is no volume letter at all (apparent in that window anyway).

Quite how the partition gets identified in that way is a puzzle, but you might try a free partition manager, such as gparted and see what that says, and possibly allows you to change. As I say above, Paragon Partition Manager might let you de-assign a drive letter but I dont dare try it myself

I have 2 HDs, both 120GBs.

I have one that's a main that I formatted into two partitions (we'll call it C and D). The other (we'll call it E), I had unplugged while the formatting was going on. I also have 2 DVD-ROMs (we'll call them F and G).

I'm not sure what's going on, but after the formatting went fine and it pulled up both C and D, I powered the PC off, plugged E back in and now Windows won't assign it a letter! It shows up in Computer Management just fine, but when I try to assign it a letter, the only option it gives me is Delete Partition. I thought the letter was being used, so I assigned D, F, and G different letters to see if it would show up. Still didn't show up. I uninstalled E's drivers, rebooted, but it still won't show up with a letter.

What is going on!??!

I have a 1.2TB HD setup...created from 4 drives. 2 500GB WD, 1 80GB WD and 1 160 GB WD (western digital). I use the 1000GB (E for data only, the 80GB (C as my Primary Partition (only trusted apps), and 160GB (Dfor everything else.

Lately I noticed that my D: drive was missing, windows shows no sign of it, But all the shortcut icons are in place, clicking one results in "file missing". I got the drive to come back by using safe mode and running msconfig to load only necessary drivers, but the drive disappeared again after some time and I had to repeat the procedure.

Does anyone know what is going on?

I have a wierd problem that most of the suggestions seem not to work.
I have a HP computer with Vista basic installed at factory with no disc sent with computer. I then added an external drive on which I installed Ubuntu OS as the primary boot drive. This was needed while I was learning and using Asterisk. Now I do not need the drive which no longer seems to have a letter designation or Ubuntu OS but cannot seem to be able to use System Recovery. Near as I can tell, I need to reset the Master Boot Record back to Vista only but seem unable to do so as I recieved no disks with the Computer.
Any suggestions. I am not extremely skilled at computer technical stuff so please assume I am an idiot if responding.

I have a gateway with a 40gb master and a 120gb slave. Both came with the pc. My slave has some important info on it I still want. Recently I have reformatted my 40 with windows on it and somehow it deleted something on my 120. It still has all of my info on it, but no drive letter. It is a "healthy drive" I have been to the disk management to see if I can do anything else but delete the partition, but it wont. I have played with partition magic, but it will not do anything but add another partition on it, and still not let me access my info. All I want to do is get my info off of it onto the 40, reformat the 120 and put the info back onto it. Is there a simple solution to format, or copy the info off? I tried lots of different software, but all it is giving me is the folders, but nothing in them. Please helP!!!!!

I just connected for the first time a Western Digital My Book Essential Edition 2.0 external hard drive and it appears in my devices as My Book. I cannot access it however. There is no letter assigned to this drive and when I try to assign one using disk management, the option to assign a letter is grayed out and therefore not usable. The drive is showing in the disk management screen and all appears to be well except that there is no letter assigned and I am not able to give it one. Any ideas?

Thank you,

I have five hard drives in my system. Recently after a reboot, one of my drives "vanished"
I rebooted again, it's back. SMART shows the drive is flawless - I suspect a loose connection or something.
My problem is that before the drive vanished, it was G:. Now it's D: (first open drive letter.) When I go into drive management and try to change the drive letter, it's not there. None of the drives showing have it, but it's not in the list.
I need this drive to be G: - how do I find where Windows thinks that letter is allocated and release it?Philo Janus, MCP Author: Pro InfoPath 2007 Pro PerformancePoint 2007 Pro SQL Server Analysis Services 2008 Building Integrated Business Intelligence Solutions with SQL Server 2008 R2 & Office 2010 Blog @ http://philo.typepad.com/with-all-due-respect/

A:Drive letter missing after removing hard drive

The problem was that the drive letter I needed wasn't in the list.
A note for anyone who reads this in the future who does support - when working with someone who says "a drive letter is missing" make sure to understand if they mean the drive doesn't have a letter assigned, or if the problem is that the letter they need
isn't available. I saw a LOT of this while I was researching this problem - I could tell that the person asking the question was saying that the letter wasn't in the list, but the person trying to help would just point them towards drive management (where
they already were, if you read carefully)
In my case, it turned out I have software running that mounts iso files as CD drives. That's where the drive letter was - it had taken the assignment, but without an iso mounted, it didn't show up in drive management.

Hi, new to these forums so I really hope I'm posting this up in the right subforum.

Long story: My old hard drive was dying, and after installing a new one I used this "EaseUS" program to clone the old HDD's data onto the new one. This worked fine except for the fact that all of my shortcuts stopped functioning because the letter assigned to the new HDD was different from the old HDD.

Is there any easy, automatic way of making all shortcuts point to the new file path? Or do I have to manually change the hard drive letter in each shortcut's properties?

After executing the following diskpart commands to the recovery partition the WinRE image is no longer accessible by ReAgentC and recovery media can not be created:
set id=de94bba4-06d1-4d40-a16a-bfd50179d6ac
gpt attributes=0x8000000000000001
Do I have to manually mount the recovery partition every time I want to create a recovery media?


A:ReAgentC: After removing drive letter and setting GPT partition ID/attributes WIM is no longer accesible.

The Create Recovery Media utility works fine. I just ran it as a test, and it does not unhide the recovery partition at any time during the media creation process. So that partition being hidden is not a problem. I took a screenshot showing Disk Management
after the utility created the recovery on USB.

Are you using Windows 8.1? If so, was it original 8.0 and updated through the Store?
I notice that in some cases, an 8.0 original, updated to 8.1 may show errors relating to recovery. For example, if you try to run recovery, it says no recovery partition present and to insert media! But when 8.1 originally came out, you could run recovery
immediately after without having to insert a disc. Something changed over that time period... perhaps it is related to a Windows Update somewhere. Anyways, if your PC is in this category, it is possible that it is related, and recovery media cannot be made
as normal.

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:changing one drive letter all 3 partitions change to that drive letter

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 lost my Event Viewer, and had to do a repair installation to fix it. Unfortunately, during the repair install, Windows decided to rename my second HD as the D: drive... it was K: before that. Now I cannot access any of my docs, pictures, music, or videos through the normal means... they don't show up in libraries or explorer, and apps like Restorator and Sure Thing (CD labeler) cannot find them. I think that means the paths are broken..?

It won't allow me to rename the HD back into K: (it's not listed as available). I can access the data by clicking Computer > D, and I can see the data is there, but its unusable as of now. Any ideas?

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,
