Re: scsi cards fixable?

[Wayne Stewart <waynes@intergate.bc.ca>]

Was the "known good hard drive" hooked up to an Apple SCSI card before?
If so and they won't work in place of an Apple SCSI card in the same
machine 
with the same setup then it'd have to be a SCSI card problem.

If the SCSI drive was hooked up to a RamFast or other card that supplies 
termination power(Active termination) then it might work with that but
not 
with the Apple cards. If a drive requires termination power then
standard 
Apple SCSI cards won't even see it.

Note: terminatin power is  not the same thing as regular termination. 
If a terminator doesn't say either Active Termination or Term Power on
it 
then it wouldn't supply it. Alternately the cards can be modified to
supply 
Term power if needed.
