I do not think creating a new partition table generates a new disk identifier. It is just a random number created when building a new MBR. Odd but it might of always been zero from the start. If you can successfully read / write from the drive then it is probably ok.

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...
