I haven't played around much with udev rules so far. However, this looks like it might mount *all* disks with the sync option. Could you explain how it's supposed to work? I would have thought that, as was mentioned earlier, udev wouldn't be responsible for mount options. Wouldn't that be handled by udisks somehow? I've tried a "mount -o remount,sync ...", and that fixes the issue, so it's just a question of figuring out why USB drives aren't getting the sync option automatically. It used to work OK until about 3/4 months ago. Maybe a new udev broke this behaviour on my machine? Paul
