Yeah, umount seems to work correctly. I misinterpreted the fact that KDE reports an immediate unmount, but the device is not actually unmounted yet. That's probably a KDE fail. It's still odd that it used to work OK, though. > The 'flush' and 'sync' mount options are not needed under normal > circumstances (as in don't use if you don't know what you are doing). Well, without sync, I get incorrect progress bars when copying large files, and "cp" returns near-instantly. This happens even with flush. That doesn't seem right to me. Is that what you normally see? Maybe my expectations are wrong. Paul
