SUMMARY: Micropolis 3243 drive problems

I recently asked your wisdoms regarding problems that I was having
with three external Micropolis 3243 4gig drives I had hooked up to
a Sparc 20. My configuration is: Sparc 20, 1 Gig Seagate internal
(ST31200), the three 3243, 1 Toshiba 3401 external CDROM, 1 archive
150 1/4 inch tape drive external, and 1 Exabyte 8505 8mm external.

I was getting alot of retryable errors on the scsi bus, and alof of phase
errors that completely make the drives go off line. After I posted
this problem to you guys, one of the externals went offline and refused
to come back up no matter what I do.

So I went to our distributor and finally got them replaced a couple of
days ago. I went ahead and install and format them. One of the NEW
drives promptly failed a format, while the other two went OK.

I tried putting the new drive in a single drive configuration, etc...
But no luck, it failed! more day wasted.

So finally, I asked my distributor to swap out these Micropolis drives
for the Seagate Barracuda 4 gigs. Stayed til midnight formatting
and testing them.....all is well. Hoorrayyy.

These new drives not only work better, but are much much much quieter
as well.

Thanks to everyone who replied, including the app engineer from
Micropolis whom I decided not to call back until I got my replacements
and then never called him back after the replacements went bazookas.
Sorry, I already erased the list of people who replied so I can't
give proper credits. But thanks....

Again, I want to reiterate that I've other systems with single drive
configurations with these Micropolis drives and they run without a
hitch. So I don't know why I am having so much foul luck with them
on this one machine. But since these Seagates work out so well
(i have them on other single drive systems as well),
I think we'll be sticking with them for the future.
