Re: SCSI Hard Disk Limitations

What kind of drive is it?  I think differential SCSI drives will not work,
but if this the regular old 50-pin SCSI-2 style interface then it should be
ok.

Have you checked all the basics-- cabling, SCSI ID, termination, etc.?
Also, download a spec sheet for your drive from the manufacturer and make
sure the jumper settings, etc look ok.  Many drives have jumper settings
that will adjust termination power, etc. that could be affecting your drive.

If you go into advanced disk utilities and toggle through the drive list,
will it recognize the drive there?  Usually when you hook up a new,
unformatted HD and load GS/OS, it will say something like "unable to read
volume, do you wish to format?"  Maybe you need to low level format and
partition it first.

But I have tested a drive as big as 4gb and GS/OS recognized it, so this is
indeed possible, it should just be a matter of configuration for you.  And
this was on a Rev C SCSI card that I got this to work.
