OS: Windows 7 Enterprise
PC Model/Make: Dell XPS 14 Z (Less than 1 year old)
USB: 2GB unmarked; given at a conference.
Problem: My USB contains all my important files, many of which were not backed up. I need these files in a short term! A friend of mine used the USB and pulled it out while un-ejected. That, in addition with possible unforeseen problems, made the USB unreadable/broken. At first, it would show and would be fully accessible, but would quickly disconnect itself and become an "unknown" drive. Normally, recovering corrupt drivers are simple. Simply copy all the files out and format the drive. Unfortunately, this was completely broken. The computer doesn't even detect the drive. The drive doesn't show up or shows up as "Removable Disk (E:)" and is not openable. The driver does install itself.
Here are the steps I took to try to fix this:
-Used the drive on several different computers
-Used recursive chkdsk on the E drive. It returned with an error.
-Used three disk recovery tools (DDR Pen Drive Recovery (Demo), iCare Card Recovery Free, and iCare Data Recovery Free). All of these found the drive but did not find anything in or about it, just like Windows.
-Tried flipping through unused drive letters and attempted to change drive letter for the USB via Disk Management. The change didn't work.
-Tried uninstalling the driver and plugging the USB back in, reinstalling the driver. That reinstalled the driver but didn't work.
-Tried Drive troubleshooting from the "Devices and Printers" screen
I'm going to need a fix ASAP, since the files are really urgent.
