Secure Hard drive wiping?

Featured Replies


Univ of Calif @ San Diego did some interesting work on the Secure Erase function built in to most Hard drives and provide a utilty to access it....
Security concerns are probably not called for, they were open about it :whistle: and it sounds like a lot of intellectual effort went into this program:

"Our sponsor, the National Security Agency, has ended their support of our program... "

LOL ...what can I say....somehow, being a dyed in the wool 98se user, it never occurs to me to look in a Vista forum for topics of interest (but that's just me).....I'm just always interested hearing about experiences of other 98se/ME users.....I fix computers for a hobby, and it's amazing how many hand - me - downs get passed around with hard drives loaded with garbage.

But anyway, thanks for the link.....

Yep :), that is the other urban myth, or, if you prefer, total and utter lack of understanding of how a Hard disk partitioning/formatting works.

MOST people think that a good ol' FORMAT will delete anything on the HD for good. :w00t:

I guess that for years most people have gone from one excess (FORMAT) to the other (35 "voodo" passes or DoD standards), and I am afraid this wioll continue for many years to come. :(

Just for the record, and for future memory, the VISTA (and possibly Windows 7) "formatting strategy" has been profoundly changed:

The format command behavior has changed in Windows Vista. By default in Windows Vista, the format command writes zeros to the whole disk when a full format is performed. In Windows XP and in earlier versions of the Windows operating system, the format command does not write zeros to the whole disk when a full format is performed.

As often happens the info is still a bit misleading:

writes zeros to the whole disk when a full format is performed.

should be read as:

writes zeros to the whole selected partition/volume/drive letter when a full format is performed.

Ok ....MS$ once again decides to write their own standard into their OS's

What puzzles me, Hard Drive manufactures came up with their own standard years ago to securely wipe a hard drive and nobody uses it ? Maybe because it was considered a destructive wipe before trashing the hard drive?

Bugs me, they do this stuff and then years later, it's like, " oh yeah did we forget to tell you?" :sneaky:
