PROBLEM: When testing a Hard Disk 20 (i.e. non SCSI hard disk) on a
Macintosh SE, the test will always fail a Hard Disk 20, even if the
Hard Disk 20 is a known good unit.
CURE: This problem with Hard Disk Drive Diagnostic 4.0 is caused by a bug
in the software which will cause it to falsely fail a non-SCSI Hard Disk 20
when tested on a Macintosh SE. The solution is to test the Hard Disk 20 ONLY
on a Macintosh Plus.
PROBLEM: If the Hard Disk 20 was formatted on a Macintosh SE, the HD20 still
fails MacTest Drive Diagnostics 4.0 on the Macintosh Plus.
CURE: Format the Hard Disk 20 on the Macintosh Plus and test the drive again.
