  1. Why are there so many data wipe/erase methods for HDD?


    Hi, I was recovering the data of an old HDD and I noticed in the software a section to wipe all the data from an HDD. I saw fill all with 0's, fill all with 1's, fill all with 0's then with 1's, then you could select the number of times the wiping was performed...

    I was thinking, if you fill all the HDD with 0's, how in heavens one person could recover data from there?
    What am I missing?

    I've read that HDD have tracks with bumps and holes, meaning 1's and 0's. If you make all of those bumps, it's impossible to know the previous state of the track.

    :)

    Erase Data

    Hello please can someone help,

    I have an old laptop running Windows 7, which is still in working order, and I am going to give it away to a friend, but I want all my information erased off it first. I never backed up the computer via the laptop, I only ever did it through a usb memory
    drive. I have tried the restore steps ie trying to do so from image etc but all it keeps asking me is where I want to back it up from??? Please there must be just a simple way of wiping my computer clean without having to go through a back up method first
    etc?

    Many Thanks

    Aine

    Finally! An alternative to eraser...

    it looks much cleaner then the eraser so that is a big step up.
