Got question for you GS hardware gurus out there:
Every-so-often, as I'm working on my GS, I'll try to access my 3.5" drive and
both the 3.5" and 5.25" drive lights will come on. Once this happens, all I
can do is press oa-control-reset and reboot to make the drives work properly.
I have a ROM01 GS with an Apple 3.5" drive and an old Disk II daisy-chained to
the 3.5" with one of those third-party cables that allow Disk II's to be
connected to the back of a 3.5" drive.
Please e-mail responses. Thanks.

I think this was not only covered there, but there was a free controller board upgrade at one time and I seem to recall it was to fix this type of problem. What I don't remember is if it was for the Apple 3.5 or Unidisk 3.5. I have two of the older disk ][ drives (with the 20 pin connectors) connected to my 3.5 and have no such problems.. -- bsherman@mthvax.cs.miami.edu | bsherman@pro-exchange | MCI MAIL:BSHERMAN

Though my set-up is slightly different I have the same problem as Mark
mentions. An awkward way around it is to disable the 5.25 driver and
unplug the cable to the 5.25 drive, re-enabling and plugging it back in
if you plan to use it...but that is very awkward, indeed.
I checked with the local dealer for I had heard it is a problem with
the 3.5 driver but they said they had not heard of such a problem. They're
pretty good as Apple dealers go, so....?
I'll be interested in any responses to this problem. Thanks!

Yep, that's how I have to do it. Consequently, the 5 1/4 stays unplugged most of the time. This is ok, I guess, but I agree it's rather an asinine way of doing things. Anyone have a solution that is guaranteed to work? (I have a new GS, 3.0 ROM, one 5 1/4, one 3.5) Thanks in advance... -Chris PS: I tried the suggested solution (sector editing a 5 1/4 disk) but it didn't seem to work... -- \ //\-\ Chris the Silver Singer cmoir@wpi.wpi.edu \/o \/-\ (Silver Singer the Silver Unicorn) / _) \-\ May the ground run swiftly beneath your feet...
