Hello! I'm doing some web-work for a fellow Mac-owner, and also keeping an eye on how his computer is running, as he's a musician with absolutely no interest in that side of things, and is liable to erase crucial files or do things which are generally unhelpful. Anyway, it's a mirror-drive door dual 867, which is quite a marvel to behold. The other day it was crashing continually (he has to run in OS 9 because of the music programs he uses), so I decided to Nortons it... but it wouldn't boot up from the Nortons disk. Nor would it boot up from the OS 9 disk. My question is: what tools should I use to check and repair and defrag his disk etc, if Norton's won't boot up? And, for that matter, WHY won't Nortons boot up? I can't find anything on Apple support about this, but then, I can never find anything on Apple support... I don't think we speak the same language. Any help / suggestions etc would be most appreciated.
