Some of the magnets are strong enough to hold a shovel, rake, 3# slegehammer! BE VERY CAREFUL WITH LAPTOP PLATTERS! Some of them are glass-like and if broken are extremely sharp.

The cases are aluminum, and good to be recycled, the magnets in them are awesome Samsungs have the biggest magnets), and the platters have cool physical properties.

Some pc shops will save them for you, if you ask nicely. I test drives constantly, since I have a couple hundred pounds of used drives lying around. HDDScan is a favorite tool for testing drives. Then I put the clone back on the original. After 3 passes, I think it’s erased well enough for me, and thoroughly tested for speed and accuracy. I do a clone of each drive then erase and benchmark the original every couple months, just to truly check the health of the drive and to “freshen” the platter. I use Both the newest and older v.25 (which I prefer for fast and dirty erase and rough benchmark). When I erase entire drives, I am also testing it’s performance.
