UNIXPC Bad Blocks & 3.51 Diagnostic Disk

	With the talk about Bad block errors in /usr/adm this just came
to mind.  A friend of mine pointed out that there's a "NON-DESTRUCTIVE"
surface test on the Diagnostic disk.  You'll have to go into the sub-system
menu (or for those guru's you can use the magic "s4test" cookie and select
it from there).  Go to "hard disk" and wait for a while as the system
does a read test and then a seek test.  You'll then be prompted if you
want to run the NON-distructive surface test.

	I know it's on 3.51, I'm not sure if it's on any of the earlier 
revisons of the system.  The test takes about 40 mins, and from what
I can gather it will add to the bad block list.  I ran it last night
but all it said was there were "12 bad blocks in table" - I'm not sure
whether it "found" the 12 bad blocks or whether they were already there.
(Lenny, you getting this?)

					Hope it's of some use,
