lost my drive letter on Healthy (Active, Recovery Partition)

Q: lost my drive letter on Healthy (Active, Recovery Partition)

After researching my issue and found this closed thread - "Windows 7 won't read drive in explorer" I started my own little research to my problem.

First some basics: I am running Windows Ultimate 32 bit. I have 2 SATA Hard Drives (one with OS), 2 SATA DVD and Blu-Ray Drives and 1 IDE Hard Drive which is configured as a slave.

Second - I needed to do some hard drive trouble shooting for another computer that had a (possibly) dead IDE Hard Drive. To do this I shut down my computer, and attached the (supposedly) dead IDE Hard Drive in its place.

Now - all the trouble began.

After booting into the Bios, I noticed the supposedly dead hard drive did not register even though it was spinning. I kept booting into the OS to see if it would be recognized in any case - it was not.

I put my working IDE Hard Drive back in - after shutting down and removing the dead IDE Hard Drive.

I booted back into the BIOS and noticed my good IDE Hard Drive wasn't being recognized either. I then went into advanced Bios settings and walla - it saw my hard drive but said I needed to reboot.

After rebooting I noticed the same thing with the Bios, but this time proceeded to boot into the OS.

After signing on, I noticed my Good Hard Drive was no longer recognized in Explorer.

I went into Administrator and Computer Management and then into Disk Management.

What I saw puzzled me as over the past 25 years I never have seen this. My good hard drive was showing up as Disk 0 and showed the 2 partitions. The only option I was allowed was "help" or I could change to a Dynamic disc. I immediately stopped as any further action and I knew I would destroy my data.

I booted and investigated several times to see if this bug would work itself out - it did not. Now I began to worry because I did not back up my important files (STUPID I KNOW) for over a week.

I read everyone's posts in a frenzy (as I am sure everyone has experienced this panic mode).

I realized I did not do anything dumb with my hardware and I could only think of all the updates Windows does every damn single night as I shut down my computer - ugh - how freakin' annoying (yes I know I can change that setting).

I then decided to try something. I restored my system to a restore point of several days ago.

BAM! My Hard Drive came back - woohoo!

I stepped away to have a quick lunch thinking I just saved my *** 10 times over and said I would not do anything until I backed everything up.

Well - of course Windows being what it is, while I was away for 30 minutes or so, my computer decided to do an auto update and reboot . And as you might be thinking right now is that - yes - it did - lost my hard drive again.

Okay - so now I'm not sure if my hard drive is going bad - it could be going intermittent on me - or if Windows is updating some driver causing this to happen.

So I did another restore from the same point as I first did - OMG - it did not work! Frenzy time again!

I then got down on my knees and prayed. "Dear Lord - if I go back one more restore point and this works - do not leave the computer and back up the files immediately."

YES!!! It came back!!!! Without flinching I immediately went into Explorer and copied the entire hard drive to another SATA working hard drive.

While copying I went back into Administrator and Computer Management and then into Disk Management and noticed that it was still not recognizing my hard drive with a letter even though it is seeing it in Explorer - wow -

As I type this I am not doing another dag nabbed thing until I finish getting all my data off.

In final: It could be a problem with my motherboard - it could be my hard drive dying - it could be Windows 7. Bottom line - BACK Up BACK Up BACK UP. Oh - and don't do a diagnostic for another computer's problems (even if it's my work computer - that I tried fixing at home) on your own home or business computer. Lesson Learned - (again).

Good Luck to all those who are experiencing FRENZY right now and I wish you success in your recovery.

Preferred Solution: lost my drive letter on Healthy (Active, Recovery Partition)

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

A: lost my drive letter on Healthy (Active, Recovery Partition)

Go into control panel and change windows update settings
to something other than automatic,like download and notify.
That way you have a choice what to install.
Then run windows update manually.
Check the list of updates for a drive controller driver.
It sounds like it is installing one that isn't working for you.
It would probably be under optional updates.
You should be able to select hide update an click ok
so it won't try to install it anymore.

The drive letter of my boot/active Win7 partition should be C:, but in my case it isn't; the boot/active partition drive letter is F.

I've tried to move heaven and earth to change the drive letter of the boot partition but nothing works.

So, aren't there any apps, tools or utilities to change the drive letter of my current boot partition?

Thanks in advance,

A:Changing Drive Letter of Boot/Active partition

Nothing that I know of. My original Win 7 installation was "E" drive. I had considered things suggested but finally decided to let it be. It doesn't matter to Windows what the drive letter is, everything works regardless of the drive lettter. I later installed Windows 7 on an SSD drive, with a clean install (and the SSD drive the only drive connected during installation) and now back to the "C" drive.

I have two "Healthy (Recovery Partition)"s and a "Healthy (EFI System Partition)" that were not there when I got my laptop and that I cannot delete. I have a Windows 8 laptop (recently updated to 8.1) and about a week ago I decided
to dual boot "Ubuntu 13.04". I only gave it a small 18.55GB partition of my hard drive as I wanted to use Windows as my main OS and Ubuntu simply to make and Linux versions of games that I create. I noticed after doing so that it added a "Healthy
(Recovery Partition)" to the beginning of the drive (the first one listed).
I could never get it to be added to the Windows boot loader correctly with EasyBCD and I had to keep going to the boot options to pick the GRUB2 and then Ubuntu. I really didn't want to keep doing this and I was having some problems with Ubuntu video
drivers as well. I figured that I would just use a different computer for Ubuntu so I took it off of my laptop and formatted the partition it was on. It worked okay but there was still that first "Healthy (Recovery Partition)" that I couldn't
delete but I just ignored it.
After updating to Windows 8.1, I thought that maybe the boot loader would work so I tried partitioning and installing Ubuntu again (I know, mistake) but it still didn't work and I could even get it load up correctly. So I finally gave up and have completely
decided that I will never dual boot a Linux with Windows again as Linux... Read more

A:Can't delete extra "Healthy (Recovery Partition)"s and "Healthy (EFI System Partition)"


According to your description, I suggest you try using Diskpart command to force-delete it.

Please perform the following steps:

1. Open a command prompt as administrator.
2. Run Diskpart application by typing Diskpart in the command prompt.

3. In the ?Diskpart? prompt, enter rescan command and press Enter key to re-scan all partitions, volumes and drives available.

4. Then type in list disk and press Enter key to show all hard disk drive available.

5. Select the disk that contains the partition you want to remove. Normally, with just 1 hard disk, it will be disk 0. So the command will be:

Select disk 0

Finish by Enter key.

6. Type list partition and press Enter key to show all available and created partition in the disk selected.

7. Select the partition that wanted to be deleted by using the following command, followed by Enter key:

Select partition x

Where x is the number of the recovery partition to be removed and unlocked its space. Be careful with the number of this partition, as wrong number may get data wipes off.

8. Finally, type in delete partition override and press Enter key.

Hope this helps.

My system will not boot. It gets as far as the Windows XP logo with the 'busy bar' going back and forth, hangs for a while, and then reiterates the entire reboot process. Starting in Safe Mode reveals a hang at MUP.DLL.

The Windows XP Setup program does not recognize the partition as being NTFS formated (my 160GB hdd has two partitions, the second one is ok).

I booted Partition Magic from a bootable CD and discovered that the primary partition has no drive letter allocated to it.

How can I restore drive letter C without erasing the entire operating system?

I am using Vista Home Premium. I have 340GB HD, which is partitioned into 3 parts. One is C. Second one was D. I had dual boot enabled, with OpenSuSE running in it, which I removed yesterday. All was fine and I was able to boot just with Windows without Grub boot loader. In Disk management application, I could see the partition - where SuSE was there earlier, as Free Space.

C drive is 64.5GB, D drive is 97.7GB. Both are NTFS. and Free space is 173 GB.

So far so good. Then instead of trying to create a new Drive/partition in the 173 GB Free space, I tried to extend the existing D Drive using PartitionMagic and somewhere in the process, I lost my D Drive I can no longer see D Drive in my Explorer (

Currently, I can still see old D drive as a partition, in blue color in Disk management software, indicating that it is a Primary partition. But I am not able to assign any Drive letter to it. Diska Management app does not show me the properties for this partition. I get this error "Operation failed to complete because the Disk management console view is not up-to-date. Refresh the view by using refresh task. If the problem persists close the Disk Manage,ent console, and then restart Disk Management or restart computer".

Restarting did not help.

Third party tools, like Active UnEraser etc are able to detect this partition as NTFS and also able to find all the files in this. So I am assuming by data is in there still.

A:NTFS partition drive letter lost. Unable to assign

Hi Sekhar, It sounds as if it doesn't matter about the files on D:\ now if I understand you correctly- that was where you had Suse installed. It also seems you can still boot and run Vista.

So it seems that you just need to clean up the partition table.

You can try this free tool (recommended) - which supports partition table recovery-
Magic Server Partition Manager Software - Resize partition for Windows Server 2003, 2008 and 2000.
- bootable CD here
Partition Wizard Bootable CD allows user to boot computer directly to manage partition.

But when I get to the part where I tell it to transfer it tells me there is not enough room for my drive D:. The recovery partition is named D:. What I have done so far: 1.) I made a recovery USB drive using Windows 10 Disk Management software. (I thought that that software would enable me to delete the recovery partition after the copy but it did not do that). 2.) I have tried to delete the partition using Windows 10 Disk Management but that is not an option. All I want to do is delete the recovery drive D: (I have the recovery USB Drive) and create a new D: drive partition. Does anybody know what I am missing here? Also, who was the person that chose D: as the recovery partition???

Hi Guys,
My sister has just brought a Dell laptop, (not sure which model), which came pre-installed with windows vista.
The hard drive has been partitioned into drives "C" & "D" - drive "D" contains the system recovery data and is called "recovery disk".

I need to change the drive letter of "D" to something else as they have some software that only runs from CD and will only run if the cd is named drive "D", so I would like to rename the "D" drive to "L" and then rename the cd drive to "D".

I know how to change the drive letters but I'm concerned that in renaming drive "D" the recovery programs won't be able to work if she ever needs to recover the system.

Does anyone have any ideas about this please?

having to configure a new HP laptop with pre-installed Win7, I need to create some extra logical drives to organize things better.

Unfortunately, the usual OEM scenario applies: all four possible primary partitions are already happily taken by the manufacturer:
SYSTEM (no drive letter),
Recovery (D:),
HP_TOOLS (no drive letter).
(Why can't they just make one partition Extended to begin with...)

However, this thread and similar ones here contain excellent info*, so I know already what can be done. I don't want to touch SYSTEM, and don't want to remove Recovery or HP_TOOLS; so the only option for me seems to be to turn (C:) into an extended partition, then shrink, then add logical volumes as required.
Sounds feasible enough**.

The one remaining question I have is rather simple:
Is it possible to then assign another drive letter than the original (D:) to the Recovery partition?
The point being that I'd like the user (not me) to be able to use drive letters C:, D:, and E: (with Recovery being e.g. R:), so that she is not confused by, and always has to think about, having to "skip" D:

On this forum I found some statements saying no it shouldn't be done (because then the F11 boot into recovery won't work any more), while others say yes, it can be done with no ill effects.

Any "authoritative" answer to this?
Would it even be possible to remove any drive letter from Recovery, so as to make it "invisible"?

Thanks for any tips!

A:Assign another drive letter than original (D:) to Recovery partition?

Hello Tronje, and welcome to Seven Forums.

The Recovery Manager in Windows 7 and at boot/startup (F11) uses this Recovery (D) partition to start the factory recovery process. (in Windows 7) HP Omni 220-1100 Desktop PC series*-* HP PCs - Performing an HP System Recovery (Windows 7) - c01867418 - HP Business Support Center
(at boot/startup) HP Omni 220-1100 Desktop PC series*-* HP PCs - Performing an HP System Recovery (Windows 7) - c01867418 - HP Business Support Center
Removing the drive letter from the Recovery (D) partition would cause you to no longer be able to open the Recovery Manager in Windows 7. I'm not sure if at boot/startup (F11) would still work or not. You would have to test afterwards to see. If not, then you would need to add the drive letter back.

Changing the drive letter of the Recovery (D) partition could cause you to no longer be able to open the Recovery Manager in Windows 7. I'm not sure if at boot/startup (F11) would still work or not. You would have to test afterwards with both methods to see. If not, then you would need to change the drive letter back to (D).

I have two virtually identical Dell laptops running Windows Home Premium.

On one of them I wanted to see what was in the hidden RECOVERY partition so I fired up Disk Manager and added a drive letter. Nothing in the partition made sense to me so I removed the drive letter.

However, windows no longer recognizes the RECOVERY partition. If I run standard windows "Create System Repair Disc", I get an error message "The parameter is incorrect 0x80070057".

The Dell DataSafe program also says it cannot find the RECOVERY partition.

a) Is there some kind of attribute that got changed when I assigned the drive letter and then removed it? If yes, how can I set it back?

b) The laptops are virtually identical. Can I use a recovery disk from one on the other? I'm particularly interested in keeping MS Office 2010 Starter edition intact when I upgrade to Win 7 Pro.

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 have a question.

I formatted a partition of my harddrive but in the end not only a partition was formatted but the next partition also was gone.

Meaning: the data is still there, but the NTFS partition isn't recognised anymore by Windows, and in diskmanager the space is now ready to assign new partition.

In a data recovery software, I saw the not recognised partition was still recognised as 'NTFS'.

What can I do?

The best scenario would be to simply tell Windows somehow, there is partition with NTFS and it should assign a letter to it.

Hi guys,

Been doing my best to sort out a troublesome PC, and this forum kept coming up when googling, so thought you guys might be able to help out! Up for a challenge?

I have made some attempt myself using tutorials, but can't help but think I should have posted first... Anyway, what's done is done...

Setup: Win XP Pro (SP2) with three logical drives:
Physical Disk 1 (200GB SATA - NTFS): Logical Drive C: and D: (C: containing Windows)
Physical Disk 2 (IDE - FAT32 converted to NTFS): Logical F:
Physical Disk 3: (300GB SATA - NTFS) Logical G:

Long story short - some bad (new) RAM was causing my screen to BSOD and restart. Before I could properly diagnose that (it killed an audio driver, which continued the BSODs even after the RAM was removed), a BSOD restart killed one of my hard drives - G (Physical Disk 3). Windows would not boot with it plugged in (moaned about hal.dll missing, even though it's not the Windows drive - booted fine without it plugged in!), and from Windows Recovery Console it was dismissed as having "Unrecoverable Errors" when trying to DIR or CHKDSK.

On advice, I tried 'bootfix', which made it an empty 10GB drive, FAT format.

A:File Recovery On Lost Ntfs Drive/partition?

Each time that you access the disk (even during bootup) the chances of losing your data increase. So limit your disk accesses as much as possible.A data recovery program attempts to check the structure of the disk and see if it can find anything that it recognizes as files. Since you've already performed some of the tests that we'd recommend, I'd have to suggest that you consult a commercial firm that specializes in this sort of thing (and they are expensive!).Other things to try would be the NTFS GetDataBack tool from http://www.runtime.orgIt allows you to scan the drive (for free) to see if anything is recoverable, then you'll have to pay to do the actual recovery (about $80 US the last time I checked)Others here have recommended a free tool called Recuva, and other free tools may also be listed here: http://www.bleepingcomputer.com/forums/topic3616.html

Hi all,

Here's the story. I had a laptop with Windows 8.1 that I got a few years back. A month ago my child knocked it over, destroying the power source. I was able to replace it and after that my laptop started fine once, but then it simply died. No odd noises came from the HD so I assumed it was not the problem.

I proceeded on removing the HD and plucking it into another Windows 8.1 machine via converters and a USP cable, assuming that it would work the same way as all other HDs had done that I've previously recovered. It didn't. The HD was recognized just fine, but it claimed to be a "Healthy GPT protective partition" and didn't allow me to assign a letter to it so that I could access it. I tried Disk Management and also browsed around Disk Part, but was unable to make it work.

After that I attempted to use TestDisk following the instructions here:
Have you "lost" a hard drive or partition in your computer? | Tech Support Forum

Now, my drive didn't look quite the way it should have, but it was close enough so I assumed that those instructions would work for me. I was wrong. After the use of TestDisk my computer now assigns drives to it, in fact, it assigns three different drives to it, but when I click any of them it says "requires formatting" to access the data. I obviously don't want to do that.

When you see the Partition you want to format, look at the number it has assigned for that partition.

Finally, type select "assign letter J", replacing J with whatever letter you chose.

Hello.I started this post in the XP forum as I was trying to downgrade to XP on a second HD with the intention of making that the main or at least having a dual boot system. Anyway, I've come to the conclusion that my system doesn't like XP so am just trying to restore Vista on the original drive.-------------------------------I have a HP m8190a system with a HP w2207 monitor.For a number of reasons, I decided to install a second HD and 2GB more RAM, with the intention of installing XP on the new drive. Which I have done, but it seems like I can't get XP to recognise any of my hardware - its all coming up generic. Drivers don't seem to help.In the XP install the drive was assigned letter D, which was also the letter for the Recovery partition on the HP Vista drive. Which, I assume, must be why when I select the HP Vista drive on the boot menu it loads XP instead of Vista. Guessing the boot info was in that section? Or could there be another reason for this?So I called HP and they are sending me the recovery disks, which should be here in 3-5 days. What I am wondering is whether this will re-format my system, as if I was reinstalling Vista? Or will it just act in place of the Recovery partition, allowing me to boot to my original drive (which is still entirely intact, just not bootable)?Also, being that I am impatiently wanting my computer back, what would happen if I used the registry to change the drive letters? So change D (XP boot drive) to N (or something) and K (Recover... Read more

A:Recovery Partition Got Reassigned A Different Volume Letter

The recovery disks will wipe everything out and restore your system to the state it was in the day that it left the factory.
The article doesn't include Vista in the list of supported OS's - but I can't see any harm in trying it anyway (but only scanned it quickly).
I'd suggest getting the hard drive out and slaving it to another machine to save your data before doing anything else - that way, should thinks get messed up, you won't have lost your data.

Hi, I did stupid thing. I changed revovery partition to R:\ then I realized that recovery does not work anymore. I changed it back to original letter D:\ but still it does not work. Is there any possibility how to make it work again? One idea: When I look in Disk Managment status of Recovery disc is Healthy but missing Boot indication. Maybe when I make D:\ disc bootable again it could work, but I do not know how. Thank you everybody in advanceMichal Bokr

Try Testdisk.

Do you have data to recover? If so, you should attempt recovery before attemting to alter or recover partitions since that can lead to total loss of the data.

If you have no data to recover, delete all the partitions, create new ones, and format.

On xp+sp3 when using scripts to open a file on the active drive I use e.g. \Scripts\tester.ahk

which used to get F:\Scripts\tester.ahk in my case, but now I get this error message instead

I've installed several new apps recently, so am not sure if one of them changed xp, or if this is something I've done inadvertently. How do I reset it?

A:\filepath\filename no longer references active drive letter, gets C: instead

I'll do a little research into this, though admittedly I haven't toyed with scripts a lot. In the mean time, couldn't you just add F:\ to the start of the file path?

so this is an on-going problem for me. It started from a broad problem and with some help from good people, ive narrowed down my situation. I lost my restore link to the recovery partition after i installed another version of windows.
This is a ASUS x550L with a pre-installed Windows 8 inside. What i need to do is set my recovery partition as active, boot from there, use that to reformat/re-install windows on drive C. I just dont know how to do it.

I saw this links while i was searching for solutions though i dont know if i can use them.

A:Setting recovery partition to active then boot from there

I wish I had more accurate info for you, but I don't have an OEM system, so I am not familiar with how it might have been set up originally. But since you have a UEFI system, you don't really set a partition to "Active".

Since you are wanting to Reset your system to Factory specs, I assume the system originally had some process to do that which required some special key combination at boot. Do you know what that was and do you know for sure it no longer works?

If you create a Recovery Drive in Windows 8.1, does it show the "Copy Recovery Partition Contents" check box as being active?

Could you open an administrative command prompt and type the following command. Copy and paste the results in your next response.

I think your answer is going to be in the original Recovery Partition. If we had a copy of the BCD store in that partition, we might be able to set up your system to use it again as a boot option, but I cannot say for sure.

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

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

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

My sister did something to her computer and reinstalled Windows XP. The thing is that it is installed on a partition (labeled "e") with only 3 gigs. I noticed this because I tried installing more software and it said that there wasn't enough space on the hard drive.

I searched online and found that I could see both partitions using the disk management utility. When I use this utility, I can see the partition labeled "e" and the other larger partition (75 gigs) and it doesn't have a drive letter. I have tried adding a letter to it by right-clicking, and all that it shows in the menu is "delete" and "help". Both partitions are labeled as "healthy".

How do I get back to that partition? Are all the programs, drivers, files, etc. still on that partition? How can I get the computer to start up on that partition? Windows XP is now installed on the smaller partition - should it be removed eventually?


A:Partition without a drive letter

The little partition was most likely the "System Recovery" partition that came with the already installed software setup when she bought the PC.

Somehow she has clobbered (a techie term ) the main partition that contained her data and Windows installation.

If she has a set of System Restore Disks (CD's), then she may be able to use them to restore the HD to its original state...like the day she bought the PC.

If not, and it were my PC, I would use FDISK to remove everything from the HD, and then recreate a single partition of maximum size on the drive. Next Format it, and then reinstall Windows...going on from there.

I have an anternal media drive whith a number of hidden partitions which do not show up in windows. One of these partitions had become corrupted and unuseable and I would like to try re formatting it to fix the error.

In Partition Magic there are a number of drives listed. Some of the drives on the partition have assigned drive letters but the one I want to format has is greyed out and listed with a * infront of it. Partition Magic will let me enter the drive to view details and even gives me the option to format it BUT then wants to assign the drive the letter A:

If I do this then the media drive will be unable to work as it will have lost the file path it needs to record on to. I just wnat to re format this drive (with whatever freeware) and have the drive letter (wich is currently unassigned) untouched so that the media player never knows its been formatted.

File system is FAT32, partition size is 10gb, using Partition Magic, there are 2 partitions with assigned drive letters and 3 without on the 1gb HDD.

Any help or suggestions appreciated thanks.

I want to assign a particular drive letter (R) to a partition on a drive for compatibility with another computer system. However when I attempt to change the drive letter using Windows Disk Management, "R" is not shown as a choice. There is no other disk shown in the listing of Volumes with the drive letter "R", and every other unassigned letter is available, so why isn't "R" shown? If indeed R is assigned to something, how can I find out what it is?

A:Can't assign a particular drive letter to a partition

Hello coffent,

You should be able to use OPTION TWO to see if "R" has already been assigned. If so, then you could use step 4 in OPTION TWO to swap the "R" drive letter with the letter the partition is currently using.

I don't understand how, but when I installed XP MCE, it was with all other drives disconnected. However, when I went to Disk Management, it's partition is labeled G:, while W7 is labeled L: when running MCE. I want to change G: to the usual C:. but Disk Management won't permit that, and when I tried something similar with Acronis Disk Director some time back, the OS would no longer boot, so I'm not anxious for a repeat performance.

The question is, how to relabel the partition safely?

A:Changing OS Partition Drive Letter

I wouldn't and don't think you can change it, not without re-installing. As you have seen Windows won't let you change the drive letter of the partition windows is installed too. The main reason is that doing that would break a lot of programs etc. They would be looking for the old drive letter not the new one. Do you have a flash card reader installed? If yes that would be my guess as to why the drive letter got to be so high. I've seen that happen in XP if the hard drive wasn't formatted. It doesn't get a drive letter until after its formated. The other formatted drives would get C:, D:, etc. I didn't think windows 7 did that anymore but I could be wrong. Like a lot of people, I've only been using it for a short while. Now that the drive is formated it should get the first drive letter C: so a re-install should fix it. It just depends on how much that bothers you as to whether you want to do it over again.

I have Windows 7 RC on my Computer. It is on Drive C:

I got this Vista Recovry disk that came with the laptop, and I was going to use it to dual boot Vist with the Windows 7. The Recovery disk will ONLY install onto drive C, there is NO OTHER intallation options.

The Question: If I change the Drive letter of my Windows 7 Drive to Drive D: and then change the Empty partition to C: will my Windows 7 still be bootable? Even if I chagne the boot loader option of Windows 7 to drive D: ?

A:Change Drive letter: Partition containing OS

I have never been able to change an OS to another letter without bricking the OS. The only tutorials for doing so make it clear it is only if the OS letter has slipped.

What I would do is save externally a backup image of Win7 using an imaging software that will allow you to select where to reimage, such as Paragon Backup & Recovery Free Edition - Free Download or Macrium Reflect.

Then go ahead and do the Vista factory restore, shrink Vista partition in Disk Management, reimage Win7 to the shrunken space. Now boot the Win7 DVD Repair console to run Startup Repair up to 3 separate times to rewrite the MBR to Win7 and possibly configure the dual boot. If not, use EasyBCD 2.0 beta in Win7 to add VIsta.

Others may have an easier idea. You'll have the backup image as a path back, so it's worth a try since Win7's drive letter is in most cases relative anyway.

I have a triple boot desktop computer with XP, Vista, and windows 7, and some storage partitions as fat 32 and ntfs types. Each operating system shows the partitions with different drive letters. From booted in the XP it is drive G, Vista is C, 7 is D, and with the 2 optical DVD/CD drives, and the 3 storage partitions, I can change those drive letters some to allow drive E to then become available for the XP system. So is there any way to change my XP from drive G to E, such as booting to the XP recovery console and using the diskpart or map commands, or some registry edit to do this change, thanks.

Hey TSF, i'm a student, and I recently bought a 500gb External Hard Drive for use with school. I also bought a PS3 and would like to add my music and movies to that. I researched about the PS3, and learnt I needed to convert the hard drive type (not sure how to describe it) to FAT32. I decided to create a partition, so the whole thing wouldnt be converted to FAT32. But after something I did (I've used Swissknife, but it didnt work, maybe thats something to do with it), one of my partitions that was previsously unallocated space turned into a primary partition. However, it wasnt labelled as healthy or as a primary partition (im just presuming it is because of the blue on the Disk Management window), and also with no drive label.

Hello....great forum!
my C: is a SSD Id like to have back as one disc, one partition..

The 101 mb 'unallocated' It was previously listed as " reserved system protected drive" I removed and formatted its 101 mb...back to empty, unallocated, can I lose that partition??

It shows up under disc management as a part of c...but really has no drive letter at all it just shows as C:

Many thx for ideas rick

A:SSD partition on c: sys drive. has no letter 'unallocated'

Are you currently using that C as your OS partition, if so, you need that other partition as is..

101mb is roughly the equivalent of 60 photos, your temp internet files can be 10x that amount. and its not not taking up a drive letter.

Do you really want/need that space?

I have a drive here on which I have spent about 7 hours setting up just the way it needs to be. I disconnected the drive and took it to another machine to do an image of the drive in the event of a major system crash.

Long story short: I didn't get to make the image before the partition simply disappeared. I put the drive back into the original machine and FDisk reports no partitions present.

I have downloaded the evaluation version of Active Partition Recovery and I simply want opinions from users of the program, if any are here, as to how good the program actually is before I spend the money for the full commercial version. (I don't know how much money I've wasted here on software that doesn't work.)

I have viewed the screens in the evaluation version and I do see my folder names and file names. In other words, it looks good.

Does any Active Partition Recovery user care to give any kudos or caveats?

A:(Resolved) Active Partition Recovery user opinions wanted

Well, I didn't get any replies and I decided not to wait any longer. I have been needing something like this for years and I guess it was long over due.

It worked with some limited success. It recovered the partition; but, it was not bootable. Nothing I could do would make it so. I finally reinstalled Windows 98 over the existing copy. It picked up all the old settings just as an upgrade should and made the drive bootable.

I didn't read the manual so I might have missed something that would have preserved the partition's bootability. I'll read it later.

This sure beat the alternative.

Hello. Windows 10 ran a long upgrade a few hours ago - I presume it was the anniversary one - and now File Explorer can't see my main data drive.

It's a 2Tb Hitachi internal drive, which was working perfectly prior to the upgrade. It shows up in Disk Management looking perfectly healthy but with no drive letter assigned to it.

This PC has one optical drive, a DVD burner, which is correctly appearing as drive letter D. The Hitachi was drive letter E, prior to the upgrade. Drive letter E still appears in the file-tree but it has been assigned to a CD drive - which doesn't exist.

When I go into Disk Management, right-click on the Hitachi and try to assign a drive letter to it I get an error message saying "The operation failed to complete because the Disk Management console view is not up-to-date. Refresh the view by using the refresh task. If the problem persists close the Disk Management console, then restart Disk Management or restart the computer." Neither refreshing nor restarting makes any difference - the same error always comes up.

This a big problem because the Hitachi is my main data drive and my MyDocuments etc folders all refer to it, but now can't connect to it.

Everything was fine with my system until I was playing a game and the computer froze. I thought no big deal since this sometimes happens. I tried to alt/delete/tab but got nothing so I ended up turning the power off. When it was rebooting I got a message that said: Drive 3 not found: Parallel ATA, PATA-1 (CR1 IDE Slave) Strike the F1 key to continue, F2 to run the set-up utlity. I went ahead and used F1 and I had lost my F:/ Drive for my external hard drive. I ended up unpluging its USB and reinstalling, than that worked right and it recongnized it as the right F:/ drive.

Now unfortunately I've lost my E:/ drive which was my CD-burner ( I dont know if I lost both F:/ and E:/ at same time). I dont even see it in the Device Manager or "my computer". I opened up case just to make sure CD-burner came undone somehow. Naturally the connections were fine.

My hard drive C:/ and DVD player D:/ show up and work. I suspect somehow my Ext HD stole the E letter somehow.
