The sync option was in there for a while and it caused nothing but headaches on FAT/VFAT USB drives. As it stands, the sync option causes the system to viciously beat up on the FAT tables anytime you are writing to the drive (one write to the FAT and one write to the backup FAT for each block allocated). At the very least, it makes it several times slower (slower even than Windows). I also had it crap on several USB drives (literally ended up with burned out blocks due to flash wear-out that even the wear-leveling failed to deal with) when I wrote a 700Meg file to a 1GB flash drive. They took the option OUT of the hal config a few months ago. Worthy note, someone on the LKML, where I also complained about the sync option destroying flash drives, suggested that I blind copy (dd) zeros over the entire flash drive to get it to flaw out the bad blocks and replace them with its internal spares. That worked and the 1GB key has been fine ever since (even though I suspect that it ends up with a much smaller load-leveling spares list internally and may still have a shorter life expectancy if I don't treat it gently, now).
