How to Fix Missing Vista Hard Disk Partition Letter in Windows 7 ?


Icons Missing After Hard Drive Letter Changes

Oct 9, 2011

In order to download the Diablo 3 Beta to my hard drive, I had to change its letter from B to E (D3 doesn't allow hard drives named A or B... sigh). When I finished downloading D3, I switched the name back to B, and now all of my desktop and start menu icons have been replaced with the white icon you get when the path is unknown (yet all of the shortcuts still work when clicked on). When I would go into the properties menu, I tried to "change" the icons back to their normal ones, but it wouldn't work (changing them to any of the standard Windows icons worked, but trying to change them back to their default ones wouldn't go). Any thoughts? It's really frustrating.

Unable To Assign Drive Letter To Sata Dynamic Hard Disk?

May 26, 2012

I formatted and installed windows 7 64 bit in a pc which previously had windows 7 32 bit. When i booted my 1tb dynamic disk was not detected. So I went into disk management and it had listed my disk as "Foreign Disk". So i imported the foreign disk.

The drive was detected and opened. So i rebooted the pc but now the drive is still not appearing in my computer. When i go to disk management the 1tb appears but there is no drive letter assigned. When i try to assign drive letter it statest that "Specified File cannot be found"

Can't Change Hard Drive Letter To Needed Letter

Nov 16, 2009

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?

Partition (E Drive) Missing - Does Not Appear In Windows Disk Management Tool

May 26, 2012

In my Sister's laptop, running Windows 7 Ultimate x86, all of a sudden, while she was working on the computer, the "E drive" went missing which was a partition on the hard disk (I don't remember if it was a logical or primary partition). She tried restarting the system but to no avail. So, I told her to open the "Disk management" tool in Windows 7 to see if the partition is visible in there. I did this because sometimes, in my computer, my expansion drive wouldn't show but it would be visible in the disk management tool and all I had to do was to re-assign it a drive letter. But, in this case, it wasn't visible over there.

So, now I told her to download "Mini-Tool Partition manager Home edition" and install it on her laptop. On running it, it wouldn't show the partition either. It would just show "C:", "D", "System Reserved" and unallocated space. However, when I added up the size displayed by C:, D:, System Reserved and Unallocated, it doesn't add up to the actual hard disk size. It means the partition is somewhere there but not visible. Is it possible that the partition would show up correctly if the laptop is booted into the bootable image of Mini-Tool Partition Manager?

Windows 7 Ultimate X64 Will Not Mount Guid Partition Table Hard Disk

Sep 4, 2011

I have an external 3TB hard drive, USB. I used a mac to partition it, 2.25TB is HFS+ (Mac OS extended - journaled) and the other is 490gb NTFS (to use on windows). It would not give me the option to use MBR (master boot record) so i used the GUID table. It works fine on macs, but windows tells me i need to reformat it. It is my understanding that most all 64bit versions of windows can read/write a GUID disk. I do not need to boot off of the drive. this is another addition to the list of "why i hate windows"

Windows 7 On Startup After Trying To Partition Hard Disk With Spotmau 2009 Show?

It displayed a window --that the system needs to restart for partioning. So I clicked on yes. After that it tried to restart and just stops on a blank Spotmau screen doing nothing(Spotmau Powersuite 2009 --Is a computer software used for partitioning and cloning). I tried to restart and bypass this window and start windows. But it doesn't work. I don't want to lose any data. I don't have a Windows 7 Installation CD.

Partition Missing From Computer - Space Not Noted In Disk Management

Feb 2, 2012

I have a 1TB hard drive partitions into a C drive and D drive. The operating system is Windows 7 64 bit. The C drive is my every day stuff, and I use D to store media, music, video etc. Today I wanted to access the D drive and it was not there. The C drive is listed as usual. I went to Disk Management and the missing D drive was not there as well. I don't know if this explains things, but I ran a partition analysis program and it showed 500 gigs as unallocated. But that space is also not noted in disk management. Right now I am running partition recovery software to see if the files are somewhere, but it will take a few hours.

2tb Hard Disk - Partition With Data Disappeared From Computer

Jan 11, 2012

I have a 2TB hard drive which i have partitioned into 3 partitions, (249GB for C:, 1000GB for D: data, 613GB for E: data). Now the 1000GB partition which is filled with data has disappeared from My computer. It happened after installing a dual boot with linux and using the 613GB as unallocated space for the linux partitions, (I have since removed the linux and partitions on the E: 613GB and created a ntfs primary partition again).

I have uploaded a screenshot that you can see that partition is not in my computer and in Disk management it only shows by "Disk 0" and not under volumes. I have tried using 'Diskpart' To assign a drive letter but under 'list volume' nothing appears. I have also done a a partition details which shows no volume, dont know if I am able to merge the partition in anyway or if the partition table that needs to be fixed

Cannot Assign Drive Letter In Windows 7 Disk Manager

Jun 14, 2012

I was asked by a client to get data off a circa 2004 PC that has a blown Power Supply. I removed the HDD and proceeded with my usual recovery procedure using a drive adapter cable and power supply. The problem is that I can see the drive in the Win7 Disk Manager, but I can't mount the partition. Most of the time I've not had problems with Win7. It usually just recognizes the drive and assigns a letter to the active primary partition. In this case, I can see the partition, it's active and healthy, but I can't assign it a letter. In fact, all options are "greyed out" except "Delete Partition."I've also used MiniTool Partition Wizard, but without success. Partition Wizard can assign a letter to the partition, which then shows up in Windows Explorer. If you click on the drive letter, you get the "J:\ refers to a location that is unavailable ...." I can explore the partition with Partition Wizard, but I'm unable to access the files.

Here are the Hardware particulars:Old HDD: 80GB Maxtor HDD ATA, formatted with 76GB primary partition, Active, NTFS, This was the boot drive for a PC I'm using Win7 x64. The drive is connected to my machine using a SATA/IDE Combo Drive adapter connected to a USB port on my machine. It uses the standard USB to SATA Serial Bridge Driver.

System Partition Letter Change

Jun 2, 2009

The system:

Drive 1: vista boot loader, vista32, two partitions (vista on C, some stuff on D), both NTFS

drive 2: broken grub loader (never mind actually), one ntfs partition with some porn, games, and other usual stuff . named E.

so then, i copy the 7100 x64 distr into my flash drive, boot it, and install our beloved 7even into the drive 2. it does not ask me anything, write its boot loader to drive 1, lets me choose which OS to boot into each time... perfect. BUT(T):

7even named her own partition C, while drive 1 partitions became D and E. i swapped last two easily, using 7even's disk management utility. that's 1 of 3 and that's not enough. i really want 7even's partition to have the same letter as in vista. i even googled it, and didn't find any answers.

7even is still unconfigured, so it would not be a problem to reinstall it. even more, if it's really necesarry, i can move all of drive 1's data somewhere else, so i can format it.

Lost Drive Letter On Healthy (Active, Recovery Partition)?

Oct 19, 2012

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.

Change Drive Letter For Presumable Needed Boot Disk

Dec 5, 2009

Windows 7, 32 bit, 12 partitions on 3 hdd's, Windows 7 on C:

When migrating to Windows 7 I first tried to update my Vista which I had used happily for 2 years. Installation went fine, but there were too many problems after.

So I bought a new 1 GB hdd and installed Windows 7 there from scratch. It is on a partition with drive letter C. I copied most of my old partitions to the new hdd, went fine.

When trying to delete one of the old hdd's with EASEUS Partition Master Home 4.1.1 manager software, there is one partition on it (which once before was called C, then successfully renamed to Z ) which I can't delete. I has on it the following folders:



System Volume Information (locked)

-->and files:



They are only 30,5 MB in size. So I resized the partition to 1 GB.

EASEUS characterizes it as Status = System, Pri/Log = Primary. Windows Disc manager characterizes it as System, Active, Primary Partition.

My question is: Can I change the drive letter from Z to B without risking the whole system to be unbootable? (and maybe never be bootable again?) When trying I just get the usual Windows warning.
I would be most grateful for an answer explaning what and why or why not.

Hard Link Issues Related To Drive Letter

Dec 25, 2009

Yesterday night I finally got the time around to finish the fresh installation of Windows 7, and I created a hard link for both my "Program Files" and "Program Files (x86)" using the command prompt in the Windows 7 installation disk.

The hard link points to another partition(E:) which I use to store Program Files purely. However, at the time of creating the hard link using the Windows 7 Installation disc, the volume letters were different than what it was in Windows. Now when I tried to access my files from Windows, it would give me an error. To better illustrate the problem,

The image above shows the hard link in (C:) and the volume which I link to (E:)

The image above shows the hard link and the directory it links to in E:. Notice that the Internet Explorer 8 on taskbar is no longer available. On the other hand, when I tried to install Firefox on "C:Program Files (x86)", it would be put in "C:ProgramData" which appears to be a new backup system that Microsoft used in case "Program Files" folder was deleted.

I know I'm in for another re-install, but what should I do to make the hard links work properly?

Missing Partition And Unallocated Space (Can't Create New Partition)?

Jul 1, 2010

I'm using Compaq Presario CQ40-627TUMy Laptop SpecIntel Dual Core Processor T4400 (2.2GHz, 80Mhz FSB,1 MB L2 Cache)- 2048MB 800MHz DDR2 Memory- 320GB 7200rpm Hard Disk Drive- 14.1' TFT WXGA High-Definition widescreen LCD panel with brightviewtechnologynd i'm using windows 7 Ultimate on boot system partition C, dual boot with linux mint. which mean i got four partition. one for linux mint. one for its swap space. one for windows 7. one for my data storage(movies,drivers,mp3,picture and etc).last few days i try to resize my C partition (120gb) to make it smaller to gain some unallocated spaces and resize the D partition because my D (almost 100gb) (ntfs/primary/data storage) almost full. i use easeus partition master v5.01.

After done resizing and restart i can't see any D partition. so i was worried that my data will disappeared. i try to look for it but there is no Drive D even on the easeus or diskpart. the only drive appears was C Drive.i remove my Linux Mint and its swap (60gb) and thinking that i could get some more free space and do some cmd prompt windows 7 repair fixmbr thing to remove the grub. then i use partition recovery to transfer those missing data from partition D to C Drive. (appears as unformatted)i try to use partition wizard home to resize it back to 300gb. and it works. but i cant make a partition. it will disappear just like that.i also try to use diskpart,command prompt diskpard, and paragon. but also not working. the C drive was shrink but theres no unallocated space and no D drive (the new create partition). i try logical partition,primary,ntfs and fat but also not working. even the unallocated space also gone. i use almost 4 3rd party partitioning software but still got no luck with it.example:i divide 300gb into 2 partition which exist the C partition 150Gb but the other one gone. i wish theres other way than format. i also done many time. doing check disk, partition table doctor, searching for bad sector. but no errors with my hdd.

I was warned that the drive would be made "simple", but not knowing the implications, I went ahead with the procedure. Now on rebooting, windows won't load. I had made a repair disc, so was able to use it to check for any start up errors. It reported none. Moreover I used "diskpart" through cmd to find volume c: is dynamic.
