It looks like the bottom line is to commit the original defect list to the
disk, followed by a format before the drives are ever put into use on a system.

When first installing these you should run format, pull the original bad
block list, commit and format. On disks where this wasn't done I have
successfully used repair by initialising the bad block list as empty. I
can't remember exactly how this is done, but it involves guddling about
in the defect menu. It says you have to reformat for this to take effect,
but
as you haven't actually added any bad blocks this is a fib.

Hot dog - I get to answer a parc question. The format utility offers
the ability to repair ESDI, SMD, and IPI disks withour requiring a complete
format of the disk. So the answer is you take the drive offline an original,
followed by a commit and a format for SCSI drives at this point in time.
---------------------------------------------------------------------------------
I am not sure if there are any tricks you can try, but I'll give you some
advice. ALWAYS reformat a new disk. Some vendors, and Sun is one of them,
do NOT, I repeat, do NOT put a bad block table on the disk. I have had
disks tell me there are 0 bad blocks, yet when I do an original, 40 or 50
will appear. Reformatting will take about 1:40.
---------------------------------------------------------------------------------
You cannot repair blocks on a scsi drive interactively, you must write
the new defect list and reformat.
---------------------------------------------------------------------------------
It needs a low level format. When you do the low level format it will
create a new "defect list". How to do it from a Sun I am not sure. I
don't think the "format" command is low level... I think it is a high level
format.
