I don't mean that it's an IO error or a bad block, but perhaps a behavioral
problem with the flash; maybe not syncing properly before it's powered
off, etc.  If it only happens with some USB drives, I do not think
it is an ext3 issue.

Your original problem report may not have been totally clear so maybe
I misunderstand.

Can you show exactly what you did, and exactly what error messages
you received, keeping in mind that any IO type errors that don't
say "ext3" are also relevant?
