Hey what ive heard to get ride of sh17 you have to over write it with data atleast 30 times! so it cant be recovered but i guess that will take it away from the avg. user

Hey, who did you kill, that you have to be so paranoid?
If you just don't want to get busted for nude pics of
Britney Spears, just deleting is good enough.
If you have forensic experts chasing you, I'd suggest
replacing your hard drive about once a week, and
destroying the old one. Or send it to me. I'll format it
and use it in my box.
:cool:

No im not paranoid really, im actually going into the forensics security field...i was just wanting to hear some other responses on the subject....

The US department of defense standard is to overwrite the data 7 times. "i wipe my unused disk space everyday". Everyday is a bit OTT dont you think? But if your that paranoid I hope you remember to overwrite your swapfile too.

Yeah that virtual memory can be a pain but yeah i hit that too, this is why i look forward to installing FreeBSD.....

Do you know which algorithm your wipe utility uses? Have you seriously tried to recover any info that you have wiped with it? Does it overwrite file names also? It doesn't matter how many times you wipe your disk if the utility is crap. I personally use PGP's file wipe utility for the fact that it is open source software. If it has any major gaping security holes (such as not overwriting the file or its name) the world would know about -- we can all view the source code. It is sometimes possible to recover data that has been overwritten 9 times, so if you're that paranoid, overwrite it a lot...
One more point: does anybody here know if overwriting magnetic media so much can affect the life of your hard drive, kind of like an old audio or VCR tape that's been used too much?

This is a pretty long and complicated paper, but it really gets down to the intricate parts of hard drives, secure deletion of content from the drives and how data could possibly be recovered (by your hopefully hypothetical forensics officer ;)).
Secure Deletion of Data from Magnetic and Solid-State Memory
Very long and very detailed, but afaik if you truly want to know how secure your deletion methods are, this is the best resource.

just saw this thread on secure data removal - it may be able to help you out.
