| BACKGROUND LEADING TO PROBLEM:
| -----------------------------
| We received a Seagate Wren VI drive from PARITY systems, already formatted
| and partitioned for our Personnal IRIS (4D/35).  It was even setup to be
| used as disk "2" (dks0d2).
| 
| I installed it on the PI, used "fx" to be sure it was partitioned.  It
| is partitioned in the same way SGI partitions their (16 MB for root,
| 50 for swap, and the rest for "/usr").
| 
...
| The hard disk is "auto-terminating", so it does not need a SCSI terminator.
| 
| That system is on one of our satellite campuses, so it's hard to keep carrying
| equipement back and forth (i.e. carry the disk here and try on our own PI,
| or come back here and get another cable, or terminator, or anything else...)
| 
| What is wrong??  anyone have any clue??  Any suggestions??
| 
| Thank you for your suggestions,

There is no such thing as an 'auto terminating' drive.  Either it has
a terminator or it doesn't.  Unless it is a completely external drive
that is the furthest scsi device from the system, it should not have
a terminator.  My guess is termination problems, or possibly a bad
cable.

Life would be so much easier if we could just look at the source code.
