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?

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.

How to force format a flash drive? I have an 8gb flash drive and I plugged it in to a speaker that plays mp3 songs. But after unplugged it, my flash drive prompts "Please insert disk" and 0mb in my computer. I tried to view it with disk management and I saw its partition type was RAW.

I'm trying to create a new simple volume in 130 GB free disk space. There's no obvious reason why it would refuse to do so - I'm not at the hard limit on number of partitions or anything - but disk management MSC is consistently returning "Not enough space" errors. The only thing I can think of is something to do with the partition order, but if so I have no idea how to fix it non-destructively. I'm in the middle of backups on it, so deleting partitions is a no-go. At the moment I don't understand what's going on.

My backup software's profile database is expecting to backup to H:, which was the drive letter for my external backup drive back in XP. This drive comes up in Windows 7 as K, because Windows 7 has given my four usb card reader drives the letters F,G,H,I.
Disk Management will not show these four card reader drives unless media is inserted (connected vs. disconnected). I have changed the letters for F,G,I to T,U,W, but only because I have those types of cards (SD, CF, MS)...I do not have an XD or SmartMedia card for the one dang drive I really need to change.
What are my options, other than buying the cheapest SM card I can find to make the drive visible for this task? The SmartSyncPro database has many profiles, so remapping all those to point to K would be a major hassle.

I needed to copy files between two PCs and didn't have a USB big enough so I took the HDD out of my Dell Vista laptop and used it as an external drive to transfer the files I needed moving. When I connected it up to the destination PC running windows 7, the drive couldn't be seen in explorer. I had to bring the drive online in Disk Management in order to be able to explore the drive and take the files I needed off of it. All was OK until I put the drive back in the Vista laptop and then found that the drive wouldn't boot. All I get is a blinking cursor after the initial Dell logo screen. like as if the BIOS can't load the drive or something.Can someone please tell me what bringing a drive online in Disk Management does to the MBR of that drive?

There was originally just one HDD and I wanted all my "Media" to be in one partition and then Programme Files etc. in another (being C). This was just so that I could copy the entire 'Drive' I had created making moving videos and photos around easier.So I used the built in disk partition manager and created some unallocated space, then called that space Drive (A) - But now that (A) drive is full and I want to add an additional 40Gb to it from the original C, but I the "Extend Volume" option is greyed out on the (A) drive even with the 40Gb as Unallocated.

I'm currently using a Windows 7 PC built by a friend of mine, but starting yesterday, its been acting up. The problem is there used to be two hard drives I can access, Drive B and Drive C. When I boot up the computer, BIOS only detects Drive C (if I'm not mistaken), and Disk Managements as well. I realized this when all the programs whose targets are on that drive are all broken on the desktop.So Drive B doesn't show up anywhere at all.

I have an external HDD that works on any other machine I test it on, except mine. It was working and for some reason I recently needed to use it and it didn't work. It appears in device manager but not in disk management. A drive letter might not be assigned to it, I can't see it in disk management to assign a drive letter to it.

We are doing system testing on a few PC's at our company with upgrading from XP to Windows 7. While using Windows 7 and the Computer Management utility, I noticed that when you connect to another computer, and right click on the PC name, you cannot view/edit the properties like you can in XP. My question is concerning this. Is there a way to view/edit the properties of another computer using Computer Management on Windows 7?

Yesterday evening I was having computer problems so I decided to do a clean reinstall of WIndows 7. I cleaned out some partitions and then tried to put WIndows 7 on the fresh partition. The process began and then I got a mesage saying that Windows cold not format a partition on disk 0. This error occured while preparing the partition selected for installtin. Error code 0x80070057I also get a message when I restart the computer saying ¨Missing Operaing system¨ I´m guessing that that means I cant log in to fix this problem

My C: drive has been displaying a size of around 60 gb with 40 free even though it's a 300 gb drive. I thought the issue would resolve with a clean install, so I did that. Now I have a fresh install and i need to reinstall everything, but the problem isn't fixed. Below are some screen shots of the drive size:Disk Management, showing my C: Drive's full size ^Any suggestions of how I can reclaim this space?? I've tried a few things already to no avail. If you need any more information about my computer to help, let me know. This is pretty annoying, 'cause I want to use that extra space to install Ubuntu.Oh, I just rememberedWhen I look at the drive in Paragon Partition Manager, it shows the full Drive size, but says that the space that is missing from Windows is in use...

I use a lot of different usb hard drives in my shop. I have two basic enclosures, a generic one that uses pata drives on a usb 2.0 cable and an Apricon USB SATA 2.0 adapter.Suddenly when I plug in a new drive device manager does see the drive and installs it in device manager. I can see the drive in Disk Management but it has no drive letter assigned, and therefore doesn't show up in Computer. I can easily just assign a letter in Disk Management and the drive immediately becomes usable. However, I would like to get Windows 7 to resume automatically assigning a drive letter.
I have tried a program called USB DriveCleanup. What it appears to have done is remove all installations of prior USB drives and when I plug in a drive that has been in the machine previously it then goes thru the install again. Yet still no drive letter. I think the program is doing what would manually be done by going into safe mode and cleaning out all the entries that build up there that don't appear in normal mode, then removes them. Basically it seems like a shortcut to manually doing it.
I also tried a registry fix that essentially asked me to delete the upper and lower filters. This seems similiar to fix for CD/DVD drives that no longer appear in Computer. This fix also didn't work.I tried removing and reinstalling the chipset drivers. Still no go.Running Windows 7 Pro SP1, H55 chipset.

I bought new hp laptop.. it came with 500 GB harddisk, windows 7 home basic, I didn't get any windows cd apart from recovery in hard disk. My windows is installed in c: and that is the only drive that it have... now the situation..
1) I want to partition my harddisk without losing windows means I don't want to format C: drive
2) I also want to install linux in dual mode with windows..
Second question is related to first one because I don't need any method that may lead to situation like I can't install any other operating system.

I have a generic System 7 64 bit system with a 1 TB SATA drive. It has one hard drive which I have partitioned into 4 partitions, with C: being where I put all the system software. The board has mulitple SATA ports.Change considered: cloning the C: partition onto a new SSD so that I can get the performance boost of an SSD. There are some heat problems with existing hard drive so I probably need to change it out, so I would also like to clone the D:, E:, and F: partitions to a new hard drive.I have cloned a single physical drive to another physical drive, and the software (Ghost, or the like) usually handles it ok, so that all I need to do is adjust some partition sizes, and then disconnect the old hard drive and everyting is good. This includes cloning a single hard drive with multiple partitions to being cloned to a new single hard drive with identical numbers of partitions.Compared to my prior experience, is there something different about cloning one partition only vs cloning the whole drive. My proposed plan is:
1) Install SSD
2) clone C: to SSD only
3) clone D: E: F: of old drive to new drive.
4) remove old drive.

I have a dual boot system with WinXP and Windows 7 on the same drive, partitioned out. I also have a second drive which contains most of my data files.
For some reason, Windows 7 isn't seeing my XP partition, however it has no problems seeing my data drive. XP can also successfully see the new Windows 7 partition when I boot into XP.
Is there a reason why Windows 7 can't see my XP partition? Is there a way to fix this? Doing a search on this was quite hard. I kept getting all sorts of irrelevant results (most about full missing hds which isn't my problem).

Would you know how to get my disk drive to start showing up and reading disk again? It stopped when I installed Windows 7.
I am guessing the Optiarc DVD is it. I went into properties and looked at its status and it gave me "Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)"

Its a bit complicated to state my situation, anyways, I have 2 HDD, and the PC won't boot if I removed the old HDD even though I've formatted the old HDD and win7 is on the new HDD.I have 2 physical HDD in PC
(1) 80GB old hdd and noisy. (not SATA)
(2) 500GB SATA hdd and sexy.
My powersupply only supports 1 SATA connection, and I don't have a DVD-Rom.I've unpluged the (2) and replaced it with my dad's SATA DVD-Rom to clean install Win7 64bit on the old (1), after I've finished, I removed the SATA DVD-Rom, I plugged back the (2), installed Win7 64bit ISO again from the (1) on (2), then I organized everything and split the (2) to E: and F:.
Everything's fine until I wanted to remove the old noisy hdd. When I did that, the PC started to bitch on me and didn't want to boot from (2).I've tried to rename (2)'s letter to C:, but it gave me 'invalid parameter' error. I doubt that it'll work by itself since it'll need to rename all the softwares' locations and stuff.so I went through another way, renaming (1) to a random letter like K: and wishing that'll work, I've restarted, shutdown'ed, and unplugged (1), didn't boot from (2).So it left me with only and only solution is by clean install, -but- I can't do it since I don't have an old dvd-rom nor do I have 2 SATA PSU cables... so I go back to the begging and...know that I have only 1 option by installing the win, is by the iso.
Now, what I'm thinking is that there's a possible way(maybe?) that I can replace Disk 0 box by Disk 1 box.Here's a picture to clarify it.So that's it, notice the 2 boxes down there? I'd like to switch Disk 0 by Disk 1 and then remove the old crappy 80gb hdd.

After adding two new SATA hard drives in my computer, I noticed that Disk Management lists SATA Drive C (which contains Win 7) as Disk 2. The other two drives are listed as Disk 0 and Disk 1.Since I connected SATA Drive C in SATA port 1, I was expecting to see it listed as Disk 0. SATA drives D and E are connected to SATA port 2 and 3 but are listed before the one connected in SATA port 1. And since the computer seems to work fine, I'm wondering if the disk numbers listed in Disk Management matter at all?
