All this is true *if* the drive behaves at a hardware level exactly like
Apple's CD SC.  The firmware on the card sends the SCSI command that our drive
expects, as does the GS/OS driver.

Some of the third-party Mac hard drives do not behave like Apple's drive yet
work fine anyway because they're shipped with a Macintosh drive.  If this is
the case, the drive will *not* work with GS/OS without a driver and may not
work with ProDOS 8 at all.

Check the facts before purchasing.
