Hi,

Although I'm somewhat personally biased, since I wrote it ...

<plug>
I think the best way to securely erase (or "wipe") disk drives
on MPE/iX *or* HP-UX is via our WipeDisk product.

MPE: http://www.allegro.com/products/hp3000/wipedisk.html
HP-UX: http://www.allegro.com/products/hp9000/wipedisk.html

WipeDisk has four modes of wiping you can select from:

   NISPOMC One pass over the disk (write)
   (meets NISPOM section 8-306, option "c") 

   NISPOMD Four passes (3 write, 1 read)
   (meets NISPOM section 8-306, option "d")

   HIPAA Six passes (3 of (write, read)) 
   (meets Department of Health and Human Services requirements)

and the most ridiculously toughest:

   ACSI33 Nine passes (W,r,W,r,W,W,W,W,W)
   (meets the Australian Government's Department of Defence's 
   Information Technology Security Manual ACSI 33, section 3.4.39, 
   2006-09-29) 

NISPOM refers to the U.S. Department of Defense 5220.22-M National 
Industrial Security Program Operating Manual (NISPOM) January 1995 
Department of Defense - Department of Energy - Nuclear Regulatory 
Commission - Central Intelligence Agency U.S. Government Printing 
Office ISBN 0-16-045560-X (see section 8-306, Clearing and 
Sanitization Matrix, option "c").

Additionally, WipeDisk has the necessary special support for wiping 
all disks on a system as well as just for wiping a single disk.
