Subject: [Hampshire] Data Destruction
Hi all



Yes this old chestnut again. Like most of us I guess, I have quite a few
old hdds and we're now in chuck away mood. Physically I'll be disposing of
these in as environmentally friendly a way as I can but destroying data is,
as I remember, a bit tricky. I know data can be recovered even if you wipe
the partition etc so here's my plan - any ideas how robust this is??



Essentially without a safe data shredding program, I'm going to use
truecrypt to create an encrypted partition over whatever data was there
beforehand. AFAIK this must overwrite what was there with a blank drive
(not just a new partition table) which could only be accessed if they
guessed my truecrypt encrypted password. So at best, someone could only
ever get back to the blank encrypted drive - not the ntfs partition that was
there before I "formatted" it with truecrypt.



I guess anything's possible but how decent a solution is this?



Cheers

Rob
