I just had this problem myself. What I have found is you can't umount a directory you are accessing on the disk. You must first cd to the directory you originally mounted from to umount. >However sometimes It > appears that the device should not be in use, yet I still get this > message. ps -a does not give any clue (shows no process running that > should be using the device).

I've used fuser in this manner, fuser -m /dev/fd0 when my floppy drive was busy, which gave me a readout, 254c 268c I ran ps aux and found two processes corresponding to 254 and 268 I killed both these processes and successfully umounted the floppy. hth, Kent
