Re:

Not true, according to NIST Special Publication 800-88 "Guidelines
For Media Sanitization":

   Clearing information is a level of media sanitization

Now, some people (including the above document) distinguish between
"clearing" and "purging":

   Purging information is a media sanitization process that protects the
   confidentiality of information against a laboratory attack. For some
   media, clearing media would not suffice for purging. However, for ATA disk
   drives manufactured after 2001 (over 15 GB) the terms clearing and purging
   have converged.
 
But, such distinction does not mean that "clearing" isn't a method of
sanitizaing.

> Option "d" does sanitize, but not for the higher levels of security.

"d" is still a method of sanitizing ... it just isn't an acceptable level
for some needs.

nope...no access to that from MPE or HP-UX :(
