    personally I store my sensitive work data on a different drive and keep it.

    and i mean keep it because I would get fired if it got out(got like 4 now over the years). I horde all my pc parts really:shadedshu

    heat more precisely >> fire is the most effective way heat destroys the plating on the platters turning them to dust Rendering the drive 100% completely unrecoverable even by advanced lasers

    I use hdtune and some others, anything that writes 0's basically works but only full format.

    Gutmann's algorithm is the best (as in most destructive to data) way to erase data.

    I use DoD 5220.22-M algorithm to erase data. It isn't the best, but most of the data won't be recoverable.

    If the drive is not important to me, I usually try to dismantle it (deforming the platters in the process), and putting a magnet directly on the platters.

    The absolute best way to destroy data on a hard drive and likely the hard drive too is to use a degausser. They often cost $3000+ though so not very practical for small outfits. If you want the best of the best, find a degausser that has the NSA (National Security Agency) seal of approval. Here's an example of NSA approved device and it runs for over $21,000: http://www.datadev.com/degausser-sdd-master.html

    If you are running a business, you wouldn't want your competition to get hold of your old disk drives.

    HDD platters are metalic, I'm pretty sure they don't "burn and turn to dust." Last I checked, heated metals melt not burn. Yeah, melting them will do that, but I'm sure a sledge hammer is the cheaper option. a 7-pass or 32-pass zero-out should work just as well too.

    I think your right, since the SSD will write to blocks with the least number of writes. However someone who wanted to recover this data would have a hell of a time because SSDs relocate sectors and blocks pretty often to reduce SSD wear on writes to distribute writes out along the entire drive.

    1 - Turn on HDD.
    2 - Attach rare-earth magnet to either side, top or bottom.
    3 - ???
    4 - PROFIT!

    PROTIP: Slide the magnet around the HDD for maximum performance!

    You will destroy the data but you could damage the drive itself or the read/write head if you use a magnet too strong. Also you might not scramble everything if you use a magnet not strong enough. 7-pass format makes for a good test to make sure the drive is reliable as well.

    If the drive is still functional, someone might still try to recover some data off it. I want the data to become non-existent and unobtainable. Even if it means killing the HDD.

    use a torch

    The only sure way I know of is to use a torch. A real torch as in acetylene/oxygen. The flame burns at about 6,330 °F (3,500 °C). You wind up with a small puddle of metal.
    Take the drive cover off and melt the platters, takes all of 5 seconds, gone forever.

    Anyone can break a drive. The trick is to looses the data and same the drive

    I simply hit the delete button and the data is gone... :wtf:

    Not true. Only the record on the file system is deleted. The data is still there until something else writes over it, unless you're using an SSD with TRIM and/or garbage collection.

    I take the platters out and use them as Frisbees in areas with lots of concrete.

    One of the funner ways to make sure your data is safe!
