[comp.unix.ultrix] Maxtor 760M drives in Ultrix

edwards@dogie.macc.wisc.edu (mark edwards) (10/12/89)

I was told the largest hard drive that Ultrix could handle was DEC's
RX55 (a 300M +) drive. Is it possible to use something larger, say 
Maxtor's 760M drives?


This is for a DecStation 3100, VAXstation 3100, 3200 if that makes any
difference.

thanks,
mark

I'm currently using a 730Mb Wren V, and Ultrix is very happy with it. So,
yes, you can probably use the 760Mb drive.

wuarchive.wustl.edu is a DECstation 3100 with two Imprimis (CDC) Wren V
disks (600M each, formatted) and an Exabyte (2GByte 8mm tape backup) and
it works perfectly.  We have just ordered a third Wren V and are trying
to get our greedy little hands on one of the new Imprimis Elite disks (1.5G)
for testing purposes.

I talked to a Trimarchi sales guy recently. They advertise a 300+MB disk
for around $3,400, a 600+MB disk for around $4,000, a 1.2GB disk for $6,500,
and a 2.4GB disk for $???. However, he said that Ultrix 3.1 and lower
would only use a ~100MB disk or a ~300MB disk as a boot device. Apparently
it checks the number of cylinders and all that hardware stuff. He said
after that the other disks worked fine. In fact, they sell a combo called
the DataStation 1000 which includes a 300+MB disk (to boot from) and a
600+MB disk in one package.

Our only drive in our VAXstation 3200 is a Maxtor XT8760E (760 MBytes
unformatted) with a Dilog controller.  When I installed Ultrix 3.0, it
identified the drive as an RA80.  I agonized over this for a while,
finally deciding to let the installation continue.  I ended up with
an RA80 with 1,271,400 sectors, instead of the "standard" 237,213.
So, with the default partition table, partitions c, f, and h are
longer.  It's been working fine for a couple of months now...
