Take a look at the output of the dmesg command.
If you see any read / write errors pertaining to the flash drive then it is might be going bad.

My first guess was the drive was bad and expected the format to fail...

Nothing looks out of the ordinary. Those messages are just the system enumerating the drive. Have you tried writing data yet?
