I wiped my HDD with a magnet. Any way to fix?

Solution
If you really have managed to erase anything with the magnet then the disk is now unusable. You will have scrambled the low-level formatting information.
Hey Matty175. Actually I'm a bit curious what type of magnets did you use, because most of the magnets one can find lying around are no wear near as powerful as they should be to wipe a hard drive, although it might damage the part of the data and the partitions for that matter. I'd say that if you've done that well you probably won't be able to recover any data from it. 🙁
 

Im not really interested in recovering data but to be able to reuse the hard drive again.https://drive.google.com/file/d/0B4TPdoa-5NO3dVZycEVweU1tVHVaaVhzWndUclQyNWtSUkVz/view?usp=sharing thats the magnet I used just a fridge magnet.
