that they take the old DASD and drop them in a acid bath then cut

Never saw it happened so not totally sure it was done or not.

George,
Well it would put an end to any thought of recovery that is for sure.
Of course there was a TV episode about an acid bath .... and they did
figure out the persons identity after it but that is TV for you.
I wish I had a chance to ask an (now) ex-IBMer about this as it is an
interesting issue. I am sure that security means different things to
different people/companies.
I would think the government has some sort of guidelines in this area
as to how erase the data. What gets interesting on the "new" type of
DASD is that the platters are not used for "permanent" DASD to me it
is like a virtual dasd volume (much like the 3850). The security
"erasure" would be a lot different in those types of equipment as
data is never actually deleted just pointers are "evaporated". I
would hope the manufacturer would have a really good erase program
(procedure).
