If you ran System 7 on your Mac, and wanted to use Apple’s formatting software, but had a drive not sold by Apple, you have been out of luck. That has changed. This quick hack works for most drives manufactured by: CDC, Conner, Miniscribe, Quantum, Rodime, Seagate, and Sony. This hack worked on all but one of the drives we tested it with. Use at your own risk…
1) Open a COPY of “Apple HD SC Setup” with ResEdit.
2) Open “CODE” ID=1.
3) Go to offset +$413A.
4) Change the two words there
from $222E $0010
to $4E71 $7203
Do NOT make this change if the two words are not $222E $0010.
5) Save your changes.
6) Run HD Setup. All drives covered should be available to work on.
7) After initializing, manually partition to get the maximum storage.
This hack has been tested on HD Setup 7.0 and 7.0.1 on several drives made by Quantum and Seagate. It is NOT guaranteed to work on prior or future versions of HD Setup or with brands not mentioned above.
As with all such quick hacks, use at your own risk.
