And To Paul's 1010101 etc patterns I do believe that 00000000 and 
11111111 are the only patterns the DOD requires. I dont' have the link 
handy but I seem to recall that was all they wanted. On the temperature 
comment that is likely true. You'd need to have the system shut down and 
good and cold, fire it up, and write like crazy!  Then get it good and 
ot and do it some more. Not so sure that's work the effort!


According to NISPOM 8-306 ( which superseded DoD 5220.22-M ):
"d. Overwrite all addressable locations with a character, its
complement, then a random character and verify. THIS METHOD IS NOT
APPROVED FOR SANITIZING MEDIA THAT CONTAINS TOP SECRET INFORMATION."

Either examples given (yours and Paul's) should qualify for the first
two passes.

The other "sanitizing" options are degaussing and destruction.
