I can't seem to get my USB drive to format anymore or be recognized by the file system (including gparted). How do I just wipe the whole thing and start over!?

dmesg

It looks like reading from the NVRAM chip in the flash drive has failed, or the controller on the flash drive failed. Time to buy a new drive.

  • Nooooooooo!!!!! Any way to check? – Eric Fossum Nov 27 '13 at 03:58
  • Try to access or format it on another computer. You could have a permissions issue, but I kind of doubt that. They are cheap enough that it's not worth putting too much effort into it. Amazon had some MicroSDs on sale - 16gb for ~$8, 32gb for ~$18 (USD). – Mat Carlson Nov 27 '13 at 15:05
  • Turns out it was the reader had failed. At a couple bucks, everyone should have a spare. – Eric Fossum Dec 19 '13 at 00:51
