Try detaching the disk after you are done using it, and attaching it again before you mount it. I use this procedure for my backup disk. It has the advantage of allowing me to physically isolate the disk from the computer. The disk lives on a detachable disk drawer-style cabinet; by pulling the disk drawer out an inch I severe the electrical connections between the disk and the computer. The idea is that even if the computer gets electrically fried by lightning, the disk will survive. Thus, the procedure I use is: atacontrol attach 0 mount /backup # Perform backup umount /backup atacontrol detach 0 -- Diomidis Spinellis - http://www.spinellis.gr
