Well Since My Disk is no longer a suspect, this really no longer pertains to the
original problem, *NONETHELESS* this is *QUITE* interesting ... Thus ...

Nature of problem a Sun424 could not find its defect list when selecting disk
within format. As a result, when I attempted to analyze/read the disk it would
respond ...

According to Sun Rep @ Answerline, there is nothing wrong with the disk: the
reason it could not find its defect list is due to the fact that it has an
embedded SCSI controler.

The Solution: Fake a Defect List.


format> defect
defect> original
defect> commit
defect> quit

Bee Bdibity Tha aa aa tsss All Folks!!!!!!

You should see something resembling an empty list when selecting original ...

Thanks Again To EVERYONE who responded:
