Some 68ks are notoriously fussy about this, I had this issue with a
CD-ROM drive and my SE/30s. Terminate the external drive and it might
make it work.

Not on all PPCs. The SCSI hard disk'd machines have 2 SCSI buses
(certainly 7200/8200 onwards SCSI disk'd machines, can't vouch for
x100s) so the external bus is not terminated by the CD-ROM drive as it
is daisy-chained in with the hard disk on the faster internal bus. I
think you may be confused by the fact that the external bus on a PPC Mac
is a lot more tolerant of non-terminated devices on the whole.

What is more does the IIci boot with it attached? If not it almost
certainly IS termination (or lack thereof), If it will boot with it
attached try using SCSIProbe or Mt. Everything to mount it, if that
fails check the termination anyway.
