RE: Erasing DASD-decommission an AS400

FYI - I would watch this space this year for some changes.

How adequate a method is really depends on your company and it's
regulatory requirements.

Al,

  While this does make it impossible to access the data with IBM 
provided standard tools, this does not prevent un-erasure of the disks 
and potential recovery of the data from them. Don't get me wrong, it 
would be (IMHO) prohibitively expensive to do so but not theoretically 
impossible. After a DOD level scrub it becomes even more difficult to do

so although, at least according to the DOD, still not impossible. This 
is why disks that have ever contained 'top secret' data must *ALWAYS be 
physically destroyed.
