I have a 32Gbt Kingston DataTraveler flash drive which has suddenly become invisible in Finder. Disk Utility does recognize it, but attempts to Verify it or to Repair it both fail, with the message "could not read boot block (Input/output error)".

It recommends that I backup as many files as possible, and then reformat.
Since I can't see it in Finder, could someone recommend another way to grab those files? Is there a way using Terminal? Would a drive cloning utility have a shot at working?

Thanks for any help.

Can you access another machine or even a windows machine? If so plug it into that and see if you can drag the files off of it.
