I'm running two SCSI disks on a AHA 2940 with parity checking enabled.
I have absolutely no problems at all.

Check proper termination, don't use the termination of a CD-Rom
(this caused trouble here) or best use a separate active termination !
And make a test, not to connect SCSI devices internal and external
on the same SCSI controller. Heard from people, that this may cause
trouble as well (if the SCSI controller is in the middle of the
SCSI "chain").
That's it, good luck
