FINALLY got around to putting in a new PSU in the old desktop.
Right On!: It powers up!
Right Off: It doesn't detect the master hard drive
Right Off: I can't remember if I was having this problem before or not
Right On: I know! I'll pop in a Linux boot disk and see what data I can find!
Right Off: I don't have any handy
Right Off: The machine that could make one would be this one
Right On: Time for new parts!
