[comp.misc] Disk drives

steveno@tekigm2.UUCP (07/22/88)

Does anyone have any information on TRAK disk drives for Atari computer
systems?  A friend has a model AT-D1 and a AT-D2 that are in need of some
repair.  I am looking for service manuals, schematic diagrams, or anything
else to help fix them.  My understanding is that TRAK went out of business
and I have not had any luck digging up technical information.  If you have
any ideas where I might find some of these manuals could you let me know?

		Thank you in advance,

According to james@bigtex.uucp (James Van Artsdalen):

I must agree.  Ateng has a Wren-III (SCSI interface), and it's worked
without a hitch for almost a year.

HOWEVER...

Since a few months ago, the disk has been making an arritating whining
sound.  It's the kind of noise that drives dogs (and programmers :-)) batty.
It wouldn't be so bad, but it's constantly warbling about, and it sometimes
stops and then starts again.

What can I do to make that noise go away??

I'm not a hardware engineer, and as a consultant I'm in no position
to speak for Sun, so I won't even try.  But as a point of reference, I've
noticed that the 90Mb Wrens now stuffed into 386i's seem to be manufactured
entirely without a static brush...there's just a blob of solder where the
brush used to be.

Well, *mine* hasn't failed yet.
