Yes I tried the formating utility that came with the NCR Card
but to no avail. It formatted fine but still wouldn't see the
20 missing cyl's.
Under the sunos formatter I tried to format it with the
Cyl's 1929/2, Hds 15, S/T 71, all it got me was the (approx.)
error ,
'drive reports 1528.... blocks & is configurred for 1537.....'
and lots of Sense code data from the format utilty.
Speaking of low level formatters are there any in the PD ?
Failing that the aft mentioned 'destructive test suite' ?

Darn, don't that sound familiar.
Tnx, JimL
