It is interesting that when someone does give good information about a failure, sometimes the guy that fixes it doesn't get to see it. Many years back, I had a hard disk that was causing troubles in a computer ( Convergent Tech, pre PC ). The problem only happened when the unit got hot and you could see that it looked like the stepper was missing a phase of the step sequence. I carefully noted these things in the space provided for symptoms in the return for repair form that I got from Shugart. About 2 weeks later, I received the drive back from Shugart and re-installed it. It had the same problem. Being local to their shop, I went over there and asked to talk to the tech that did the work. They were reluctant but finally said OK. On going to ask him why he hadn't fixed the problem, I discovered that he had never seen the note on the form. It was separated at incoming and he ran the standard 5 minute test, installed a new belt and stamped it passed. I made some noise about having some way to pass the symptoms on to the guy that was repairing it and they gave me a maintenance manual. It took me 15 mins to warm it up to fail and 2 mins to find the bad transistor, with schematic in hand. So, when you see the space on a return form for symptoms, you might just as well put what they expect: "Ahhh, it doesn't work, must be a short some place." Later Dwight
