RE: Recover data from As/400 Drives

I think someone with proper devices could recover data.  The chances of
it being meaningful would be very slim unless it was a single-drive
system, though.  With striping and being spread across multiple disks in
a RAID set, it would make whatever data retrieved pretty "random," if
you will.

I also seem to recall some function suggested to IBM about adding an
official "clear disks" feature to DST, never heard anything more about
it.  I thought the government required writing 1s, then 0s something
like 7 times to call a physical disk "clean."  Not sure on that number
though - may be getting it confused with number of shuffles of a new
deck of cards.

Get a disk degausser.  That'll smoke 'em.  =)  And yes, taking backup
tapes home is infinitely more risky than reselling these drives.  The
chances are very very very remote, IMHO, but auditors can (and will)
always find something.  If it's only a few, it's not worth it.

Subject: Recover data from As/400 Drives

   If I have done BOTH of:
    a) Delete ASP Data
      - AND -
    b) booted to a SLIC CD and done Initialize and Format disks for all
disks
   on a system.
    
   is there any possibilty, however remote, that data could be recovered
from
   those disks?
    
   In other words if you had disks from your company that had been
cleared in
   this manner would you be comfortable selling those disks on the used
   market?  I have a customer who believes that SOX says you cannot sell
that
   stuff because data could be recovered. I think they have 100,000
times
   more exposure by having IT staff take backup tapes home in their car
as
   off-site backups!
