Cannot Repair/Verify USB Drive
I have a 32GB Toshiba USB drive, formatted as FAT. Up until today, it interfaced fine with my MacBook Pro. Today someone was using it to copy over information (also using a MacBook Pro), and the drive glitched on their machine, and became unreadable. When I now insert it into my computer, I get the message "The disk you inserted was not readable by this computer."
If I click Initialize to open Disk Utility, and select the drive, there are no available options under First Aid, everything is greyed out. I have tried to format the drive using every available file system flavor, and the format fails each time, citing "Wiping volume data to prevent future accidental probing failed." This happens regardless of the type of file system format I try. I have not tried to reformat this drive in any other OS. The drive will not show up if I try to do a volumes search in Terminal.
System info:
OSX 10.10.5
MacBook Pro Retina, 15-inch, 2.3 GHz Intel i7, 16GB 1600 MHz DDR3
Any assistance in trying to at least be able to restore a file system to this drive would be helpful, I figure the data is a lost cause. Thank you.
MacBook Pro, OS X Yosemite (10.10.5)
