[comp.sys.amiga.tech] Hard Disk Problems

jvmiller@zeno1.rdrc.rpi.edu (Jim Miller) (10/16/89)

I have recently been having problems with my 20 meg Supra
hard disk on my Amiga 1000.  Upon mounting the disk, it repsonds
with "No partion table found" (or some such information).  I have
been able to get it to mount intermittently.  If it does mount, then
while the disk is in use, it will change speeds and decide that this
is a good time to park the disk.  It lets the disk coast to a stop and
of course locks up the computer.  I had the disk for about 2 1/2 years.
I had to send it back once (about a year after I bought it) because the
medium had gotten damaged.

I haven't gotten a chance to call Supra yet (I don't feel like being
without my harddisk for a month).  It seems to me that the controller
seems to be misinterpretting commands like "move" as "park".

Does anyone have any suggestions other than contacting Supra? 

Thanks,
Jimmy

It appears my original reply to Jim Miller's Q about problems with his HD
didn't get posted (there are still some quake-related problems zinging
PORTAL's disks) ...

my conjecture is the power supply.  I posted testing instructions; Jimmy,
send email and I'll walk you thru the procedure.  Replacement power supplies
should be readily available at surplus places in your area, and the mounting
holes are "almost" a universal standard so it can be an easy repair job.
