Johnny the success proves that I'm right. After "erasing" the disk the
exerciser run found no soft read errors anymore. "Soft error read count 0".
BTW: This was the disk that I've hammered :-)

The exerciser showed some correctable soft errors, wich is pretty much
normal I think. Reformating the drive should simply "freshen up" the data
tracks but erase should do the same in this regard.
Since the distks aren't containing anything interresting, it would be the
right time now to do a reformat.
I think the head assembly has an voice coil engine anyways, so servo tracks
are needed to do the positioning. It is clear that they aren't affected from
a reformat...
Ok, the disk passed the tests with ok.
Excellent.
I've tried to boot something from DIA0 DIA1
and DIA2..nosurchfile so the
disks seems to be empty.
Oh Well...
Now I think about a reformat of the drives, but
there is no such procedure.
There is an erase program that should rewrite eachs sector with several
patterns. I'll think that it will do the job.
Does an format programm exists "in the field" or is something like thisi
proprietary to DEC?
Why would you want to reformat the drives?
That said, I would expect such a utility to exist in the firmware of the
drive.
But normally, since these drives remap bad sectors automatically, you
should normally just go on using them, and everything is ok.
