Erasing data from a system

[Dan Rasch <drasch@xxxxxxxxxxxx>]

There is an upcoming task to purge all data off DASD for a system that 
is going off lease and being returned.  Of course deleting the data (or as
it should relly be termed, marking it as deleted) is not robust enough.
We need to physically destroy bits, or damage them beyond recoverability.    

Some years ago, I remember a process (it may have been on VM) that 
did this very task rather quickly (less than an hour, and more like 
20 minutes if I remember correctly).  I seem to remember something about
striping, but I can only barely remember having a memory.

TIA,

important things in life, there would be a shortage of fishing poles!
