I have an 8GB USB drive that shows up as 7.46GB RAW in Disk Management (it also says "Healty (Primary Partition)". I don't believe there is any physical damage to the device.

When I right click the the volume, the only options I get are "Change Drive Letter and Paths" and "Format".
The problem is, If I attempt to do any of those, I get an error stating "The system cannot find the file specified".

Using TestDisk, I can get to the "Write" confirmation, but I get "Partition: Write error"

Is there any way I can fix this (utilities, programs, TestDisk, etc)? Data recovery is not the goal here (I just want the drive to work again).

Found a solution. Use GParted; install it on a Live USB (basically creating a bootable USB) and boot from it. It'll put you in a simple Linux desktop where you can open the application and fix the drive.

Mine showed up as "unallocated" so I just created a fresh partition there. Drive is now fine and fully working!

Well, I had a similar situation and did a couple of things. Cannot confirm which one was 'the one', but it worked. I'm using Win8, btw.

  • Opened diskmgmt.msc
  • Clicked on the 'raw' disk / partition (it was the same)
  • Changed the drive letter to L
  • Applied the change
  • Opened the Control Panel
  • 'Hardware and Sound'
  • Device Manager
  • Double clicked the driver, under disks
  • On 'policies', changed to Better Performance and then back to Quick Removal
  • Disconnected and connected back the disk (using the safe removal)
  • Back to the Disk Management, mark the disk to go offline
  • Tried to format it using the format only recognized by Win8 (I can't recall now the name)
  • It failed, but when I tried to mark back the format to MBR, it worked fine

Hope this helps.
