    Question what software for completely wiping a Hard drive?

    i know there was a thread about this recently but do you think i can find it??? 25 minutes of searching & i'm still none the wiser so apologies for asking a question thats already been answered

    anyway, i'm having a clear out & have about 12 old hard drives lying around, i'm thinking of selling them but obvioulsy i'd need to clear them down properly before doing so

    since most of these have come from old machines i've stripped down i don't actually know whats been on them during their lifetime, so partly to protect myself from what other people may or may not have been up to, and partly not to fall foul of the data protection act (slim chance but would rather be safe) whats the best software for completely wiping a hard drive so that none of the previous data is recoverable

    cheers

    nope - you need to run at least a 7 pass wipe for data to be unrecoverable within reasonable limits.

    chap I know that sells old servers on ebay has to run a 30 pass wipe ( for obvious reasons ) - he sent a drive off to be tested and round that much of the data was still recoverable after the 7 pass.

    http://www.snapfiles.com/Freeware/security/fwerase.html has some good utils on it.

    A zero-write or low level format would be good enough for 99% of things. Most harddrive manufactures have zero-write software you can download.

    A standard format doesn't erase much of anything.

    I'll give this DBAN thing a try.

    Heidi Eraser is good, free, and includes a facility to create a DBAN boot disk as well.

    Because i use Maxtor Harddrives i can use Maxblast, you have 2 options, quick format which just erases the first 62 sectors or something.

    Or there is a complete zero write which will make anything irrecoverable, however it takes forever, forinstance after 10/20 mins only 1% had been done on my 80gb IDE hard drive!

    But if you want to do it properly you need to take your time

    Hmm, iirc a low level format does nothing more than reset every sector on the drive to 0, for which you can even use a hex editor, tho you will probly find that software specifically designed for clearing drives is a bit faster than a hex editor

    How do you go about finding this data that is not wiped?
    Are you saying I can find data on my old HDD's that I wiped and then put a clean copy of windows on??
