The only way to get the Disk to mount again is to use SCSI Probe 2.01 and issue a mount command, and then reboot. The hard disk then resumes to work fine. I have been trying to find a way to duplicate the problem but so far it has happens only randomly. Sounds to me that it is possible that DEII might be messing around with the system file or the finder file at the time you shut down, which might alter the boot blocks on the HD... Once the disk is mounted, you probably checked out the system folder (opening it and shutting it with a system & finder file in it would restore the boot blocks) which fixed the problem... (These are my ideas. If someone has a better idea, or knows that I am wrong for some particular reason, please tell me because I would rather be correct than proud :-) ) -- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Alan D.
