Unusual problem with my USB flash drive

This might sound a little crazy, but I've been having an unusual problem with my main USB flash drive.

Lately, when I plug my SanDisk 128GB USB flash drive into any computer, it does not want to open. On my Windows PCs, when I plug it in, the flash drive's directory (E:\ on my main desktop and H:/ on my laptop) doesn't appear in File Explorer, and when I open Devices and Printers in the Control Panel, it displays the "Ultra" device (the name of the flash drive), but without displaying the name of the USB device, and when I select it, the device status reads "Device can perform faster when connected to USB 3.0".

Now, before you give me any kind of advice, yes I did try uninstalling/reinstalling the USB drivers for the flash drive, but it just won't work and its very strange. I absolutely do NOT want to do anything will may erase everything on this flash drive because there's a lot of important files on there that I need.

If you happen to know any good ways to fix this issue, that would be great!


  • If it is not showing you the files, it almost sounds like the drive may have died. Off hand, I'd try some other computer (does it actually need a third party driver to read it?), especially if it has a different OS or versions.

    If the files are important, you might try a Linux machine and using "dd" to copy the entire block volume to a file, so you can extract files later. If dd fails, then something is wrong with the drive itself.
  • No, this flash drive doesn't require any third party drivers. Like any flash drive, it just uses the standard USB Root Hub under Universal Serial Bus controllers in Device Manager. That was what I originally meant to say. Also, not only does it not show the files, it doesn't show the disk drive at all. I don't remember doing anything that might have damaged my flash drive :\
    If my USB drive is dead, then I guess I could try out your suggestion on my Ubuntu or Linux Mint operating systems.
  • This sounds like a partition issue to me. What kind of Windows OS are you trying to use this flash drive with? Also is there any way that you could reformat the usb drive?

    If not windows, you could try it out on Linux live cd/usb and reformat the usb drive that way using gptarted. Make sure to format it to something that supports that big storage size like exFat or ntfs. Hope this helps.
