ROTFL!  There HAS been a change, and the information above is NOT true.  As I
recall from hacking HD SC Setup, it USED to FIRST check for the words
"APPLE COMPUTER INC." as the result of some SCSI command.  If that worked,
the drive was considered usable.  Then it checked to see if the type string
matched a list-- if it matched anything in the list, again, the drive was
considered useable.  NOW it checks the list, and if it doesn't show up in
the list, the drive is not usable.  THEN it checks for APPLE COMPUTER INC.,
and if it doesn't find it, the drive is not usable.  So to make it work with
third party drives-- First, hack one of the strings in the resource fork (one
of the CODE segments) to match what the drive tells SCSIProbe or SEdit. 
THEN do a search-and-replace in the resource fork for
0007 181C 660E 6000
replace with
0007 181C 6664 6000
