Anyone out there that has followed up on this situation? Yes, I did today. GVP was helpful as usual and very responsive. The problem is a chip on the Quantum drive, and Quantum has provided an upgrade. GVP will mail the chip to me (no charge) in the next day or two. Meanwhile, my harddrive is working again, except for occassional minor problems. So, I am looking forward to getting the new chip. My impression is you will have to ask for the chip. I want to thank all of the people who sent me information about this problem. I cannot seem to get email through to all addresses. Pat Palmer (email: ppalmer@oddjob.uchicago.edu)

I'm not Apple owners have also had many problems with the quantum drives, and are VERY unsatisfied with the fix Apple has provided for it. I believe it is the same fix that you are talking about. Also, as well as increasing the current at startup, it "exercises" the head's arm every once in awhile. While this is going on, disk accesses become VERY slow. Apple users are VERY dissatisfied with the fix. Supposedly, there was at least one magazine article about their dissatisfaction. > The problem >is a chip on the Quantum drive, and Quantum has provided an upgrade. No, the problem is with the grease for the spindle of the hard drive. A new ROM to increase the startup current and exercise the arm is a (problematic) fix. Refer to comp.sys.mac for more info, including a graph of the slowdown caused by the "fix". I was ready (except for the money) to buy a MicroBotics HardFrame / Quantum 40Mb drive combination, but unless Quantum fixes things SOON and does it WELL (AND shows that they won't screw their current customers), I'm going to be looking for another hard drive. Any suggestions for a good, fast, RELIABLE, reasonably priced SCSI drive around the 40-80 Mb range? >Pat Palmer (email: ppalmer@oddjob.uchicago.edu) Rodney Ricks -- "We may have come over here in different ships, but we're all in the same boat now." -- Jesse Jackson Rodney Ricks, Morehouse College
