[comp.sys.hp] Hard drive information

Does anyone know what kind of hard drive is in the 9133 hard drive systems
and can they be upgraded from the little 14.5M to something in the 20-40M
range w/o any changes to HPUX?

Any help would be appreciated

Which 9133?, The 9133A, B, D, H, L, V or XV?   Look on the back.  All
varieties of 9133 used Seagate mechs of one kind of another.

It sounds like you have either a 9133XV or a 9133D.  The 'XV cannot be
upgraded.  The 9133D would require at least firmware changes and perhaps a
new SS/80 controller board.  Even if you could get the needed information
(and I don't have it),  only specific models of Seagate mech could be used
and they are all probably obsolete,  which is part of the reason why the
9133-series is no longer made.

SS/80 drives are fully parametric,  so if you could upgrade a 9133D to
a 9133H (20M) or 9133L (40M), HP-UX would recognize it.

  The HP9133 drives CAN be upgraded. I have 3 of them that I have upgraded to
40 Mbytes each. You need to replace the old hard drive mechanism with a
Seagate ST-4051 and change a jumper on the controller board.

  Two of the drives I had used Seagate ST-419 and ST-225 drives. These are the
ones I upgraded. Be careful to record the existing jumper settings BEFORE
changing them in case you have trouble with the upgrade.

  For a rev B controller board, set the jumpers to EBxH. For a rev C controller
board, set the jumpers to EBxD. 'x' indicates leaving that jumper unchanged as
that jumper tells the controller if a floppy drive is present and should not be
changed.

  Also note the jumper that says 256/1024. That affects the physical sector size
of the hard disk. Changing it to 1024 bytes/sector will increase the amount of
storage available. If you store a lot of small files (<1024 bytes) this may not
be a good idea as it will actually waste space.

  I use these drives with an HP PACAL workstation and have had no problems.
They should also work with any HP system as this upgrade converts the drive to
a 9133L which should be supported.

  Feel free to email any questions.
