USB Flash Drive Is No Longer Seen As A Drive Or In Disc Management
Sep 26, 2012
I know, should have a backup, I was actually about to create a backup when the flash drive failed on me unfortunately. My newest backup is from about 5 days ago, so I'd prefer to be able to restore the current files.
I moved the drive over to another computer and tried to save a file but when I checked again the file was gone, like it never saved at all. Subsequently, after removing and plugging it back in the computer did not detect the drive (or see it in disc management). It does show up as a generic USB drive in the device manager, but there are no properties for it.
When I add it to a computer, it still adds drivers for it, but then nothing happens after that. It may also be a hardware problem, since the drive fell on the ground pretty hard a while back, but seemed to be working fine. There isn't an easy way to open it up and check.
I also tried using a few data recovery programs, but they couldn't detect the drive either.

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.

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 running WIN 7 on my home pc and transferred some files via a Flash Drive to a laptop running XP Pro to go on a trip. Upon my return I update my home pc with the data from laptop/FD; I've done this with no problem many times. Upon my return this time my home pc will not recognize the FD. I've updated the driver, checked Disk Management, etc all to no avail. The FD isn't recognized and neither is a second FD I tried. They both work on the laptop.

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.

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...

Before I even go further: yes, the "hide empty drives" has been unchecked)I had to reinstall my machine and I was able to to see the drive letters for the internal flash card reader. However I think something might have gone wrong when I give my external HDD a drive letter that was held by one of the flash card reader).I wrote "I think" because I am not really sure since I never wanted to use the internal card reader till today so I never noticed there was an issue. Anyway, the internal card reader does not show up even when I insert a card in the reader. Basically nothing happens. I have uninstalled the "USB Mass storage device" and it gets installed without any issue but the problem is still there: I can't see the reader. the INTERNAL flash card reader has a USB slot and when I insert a EXTERNAL flash drive, the EXTERNAL flash drive shows up.

I have a hard drive I want to backup to a 64gb flash drive and then restore it to another different hard drive than where it came from. I have windows 7 and office on my laptop and I want it on my desktop pc. There isn't close to 64gb of info on my laptop so it should be fine even though the hard drive says I have 160gb. It is all free space except for those programs.

So I have an bit of an odd and I think unique problem (as many searches came up with no solutions). Simply put, my boot manager is missing, but only when my windows install disc is not in the disc drive. It started several months ago and I just left it be, let the disc it int he disc drive and it was not that big of a deal. But just did a clean install couple days ago I re-installed windows 7 ultimate 64-bit on my computer (using an upgrade disc if that makes a difference).I formatted the drive with what I guess is a quick format (the option the install disc gives you). I have tried doing a repair with the install disc but no problems are found every time I try.

I recently reorganized my computer and this included a fresh install of Windows 7 on a new disk. I backed up all my data on the old disk so that I could make sure I wasn't losing any important documents or whatever.I'm now sure I've got everything off the disk that I needed and am using the disk as a storage disk for media. However, there are still folders that I can't seem to erase in the Program Files, Program Files (x86), and Windows directories. Most of the files are gone but about 12GB of junk remains that I no longer need. Whenever I try to delete what is left, it says I need permission from TrustedInstaller and it won't let me delete these files.Is there any way to blow these directories away without having to format the disk? I really can't format because the disk is almost full with data that I need to keep and I don't really have any other disks to temporarily back these files up to.

I recently ran into a very weird windows 7 bit problem after installing it on my desktop. I cannot copy large files/ holders into usb flash drive or write large files to cd/ dvd. The copying/ moving process would stay on for about 5-10 seconds then freezes then I get an error message. That is:
H: refers to a location that is unavailable. it could be on a hard drive on this computer...
I have all the latest drivers.
And windows/ nero 9 can't use my dvd drive to burn files.
Some info about my system: AMD X4 630 CPU. MSI KA780G (AMD 780G chipset) mobo. I have 2 sata hdds, non raid mode. The DVD drive is IDE. 4gb ram ddr2 ram. windows 7 64 bit.

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.

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 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.

Now I can no longer access my C drive, Get a message that the administrator (me) has banned me!
At the same time, I started gettin a message that my antivirus key is not valid.
Antivirus no longer works. (Avast). Also at about the same time my email programme (Thunderbird) started telling me that it could not download any more messages as there was insufficient room. Even after deleting several messages, the same fault continues. It looks like scrap W7 and reinstall, unless anyone has a better idea.

I'm not a newbie when it comes to PCs either, I build my own and repair/troubleshoot others.
For some reason, my computer stopped reading DVDs in the drive. CDs load fine and I can burn to them. I checked the hardware properties and somehow Windows has decided to install a CDROM driver to the device, which is why I believe DVDs are no longer being read. I've tried going through and uninstalling the driver and getting rid of the registry keys assosicated in order for the correct driver to be installed, but Windows keeps installing incorrect ones.This just happened a few days ago, tried restoring Windows to a week ago and same problem exists. Less than a month ago I used it to install Diablo 3 so I know it works fine.
