Okay, I don't know what's going on. But now it's working fine. I hooked up an external hard drive, is recognized and mounts on the desktop; plus I can read and write to the drive fine. The internal drive was swapped with another known good drive and it too is recognized, mounts and read/write to disk fine. I'm thinking it was a bad cable or something in the ROM SIMM was screwing up the SCSI or logic board. I also tried operating both with and without a battery in place. I can't get it to fail, like it did in the past week. Really weird.

Thank you everyone for your suggestions. In the mean time, I'll tell the owner to keep a close eye out in case this happens again and report it to me.
