when I encounter a hard-disk which doesn't want to mount after I boot from
a floppy and try to mount it with the help of the CDEV SCSI-Bus-1.0, I pull
out MacZap-Tools-5.1 and use it (and it's built-in SCSI-driver) to access
the disk, after which it shows up on the desktop when I quit Zap-Tools,
IFF I was able to access the disk with ZAP-Tools ... which is usually the
case.  I then back things up (if they weren't already), run DiskFirstAid and
MacExpress (I think there are some other useful programs I have not become
familiar with yet), and whatever other analyzing tools the disk came with ...

My Dataframe has shown these symptoms for quite some time now and I suspect
a transient failure in the boot-blocks (or some other critical area).

SUM (the successor of ZAP) may also have this ability to revive disks with
unusable SCSI-drivers, but I have not bothered to search for it, given that
ZAP-Tools does the trick for me ...

This sounds like a good time and reason to take out a pen and paper
and write a letter to Apple asking them when they will follow the lead of
Jasmine and provide some usefull Hard-Disk recovery tools and instructions.

Don't tell Apple how much you enjoy practicing your manual writing skills
again ... that would be counter-productive ....(-:
