[u3b.tech] hard disk for old 3b2/300

rk@bigbroth.UUCP (rohan kelley) (01/10/89)

We just completed installation of the maxtor xt2190 into our 3b2/400.
We formatted it to 1024 cylinders just as the net postings indicate
is the limit. (didn't even try more). It gives us 135 mb formatted and
seems much faster than our present 72 meg fujitsu M2234AS (standard
equipment).  With the idtools kit from ATT as recommended by Steve
Friedel @ vsi.com it was no problem.  

This was installed as disk 1 (the second after disk0). It was slightly 
trickier, however, to move our /usr to the new disk and then create /usr2
in the old /usr space.  The process was accomplished by first mounting
the new disk as /mount, then "find"ing the /usr files | to cpio -pdum /mount. 
When a duplicate of the /usr system was completed, we umounted both
systems, labelit /dev/dsk/c1d0s1 (the new disk) /usr and
/dev/dsk/c1d0s2 (the old /usr system) as /usr2.  Then mount as the
appropriate file systems.

This leaves / on disk 0 and puts /usr on disk1.  Hopefully that will
allow the sytem to run faster if a root seek and a /usr seek are
simultaneous.  

NEXT QUESTION! We want to install a new disk in place of the old 30 meg
on an old 3b2/300.  We understand 8 heads and 1024 cylinders is the
limit.  We understand that a good candidate for that combination is the
PRIAM ID130 available from Storage Plus at $1385.  Has anybody successfully
installed this disk or similar disk on an old 300?

We have installed Micropolis 1325's in 3B2/300 boxes
without troubles. They are 8 head/1024 cylinder drives.
