Thank you everyone, RHP for introducing me to this group, Kelly for your encouragement, neokm for the sending me to Tom for the new hard drive ($10.00!) BobW for pointing me to the service manual. I could go on and on! It was actually pretty easy, and I never would have dreamed I could do this--take out the old hard drive, put in a new (to me) hard drive and a CACHE chip ($3.00). The hardest part was disconnecting the SCSI power cable, I cut my finger on some piece of metal that was IN MY WAY. The computer was almost in the dumpster....just about five minutes away from the landfill. I feel like I'm accepting an acadamy award, thanking my crew. My little friend will be happy to have her computer back again, I told her a month ago it was a goner.
