I am attempting to replace a Micropolis 1325 70MB hard disk in our 4/260
with an as yet unpurchased hard disk in the 200-300MB range.  It appears
from the format.dat file that we have an Adaptec SCSI controller.
Basically I have two questions:

1) Looking through the format.dat file I have noticed that different SCSI
   disks are "officially" supported with different SCSI controlers.  I
   thought that SCSI was SCSI so my question is can I hook up any SCSI disk
   to our controler and, assuming I get the format data correct, have it
   work?  Or is there some rational reason why different disks are associated
   with different controlers in the format.dat file.

2) Assuming that I can hook up any SCSI disk to the controller, who is a
   good source for third party disks?  Actually I suppose I should also ask
   who is a good maker of third party disks.
