I have seen flash disk dead in 5 minutes, even without o-sync.
Those devices are often crap. (I copied tar file to flash by cat
foo.tar > /dev/sda. That was apparently enough to kill that flash.
Label "Yahoo" should have warned me).
Sometimes a flash device can have a temporary error condition that is
solved by rewriting the data. (I've seen it triggered by buggy USB
hubs that don't provide the rated power). It seems that a number of
flash drives have internal checks, and when those trigger it reports
a bad sector (even if it isn't permanently bad). My 1GB flashdrive
failed in that way, and I was able to fix the error by erasing with
"dd if=/dev/full of=/dev/usbkey" and reformatting. After the error
occurred I started md5summing every file I put on the drive, but I've
been using it for a month now and not a single checksum has miscomputed.
