I used to get the hard drive not detected message intermittently and reseating the unit would resolve the issue. I reseated the IDE cable and it fixed the problem for a while, but then it returned intermittently and finally permanently. The drive in the system made a rattling noise when moved around so I bought a replacement drive, same result. I bought a replacement cable from Eutronix, same again. Tested the contacts from the MB to the pins, seems good, tested the cable, all leads work. Both drives pass diagnostics (connected to a desktop system with an adapter) and make spin-up noises in the Rio Empeg unit when it's powered on. I can provide more details or pictures if needed. I am not an electrician but I do have access to a DMM if you have any TS steps requiring one. Thank you for any assistance you are able to provide here; the idea of replacing the unit with a non Empeg sickens me!
