Erasing hard drive with magnet

Did you know that you can erase a hard drive using a magnet? One of our customers has helped us test magnets for erasing hard drives when they are to be discarded.

We had done a lot of research before the trial to find out other people's experiences with the need for N values ​​and other factors that influence the choice of magnet. 

Strong magnet for erasing hard drives

We came to the conclusion that a 30x15 mm. magnet could be a good bet for a strong magnet for the task, and it worked. But one successful trial doesn't make us completely satisfied - we want to be sure that the solution really works and that we haven't just been lucky. So when another customer contacted us to find a solution for a workshop with quick deletion of used hard drives, it was very obvious to test it again and the choice again fell on a 30x15 mm. neodymium magnet. 

The result?

It worked again! So now we are ready to pass the tip on to others who need to erase the contents from hard drives quickly and efficiently.

Destroy mobile phone or hard disc

Be carefull that you don't destroy your computer or mobile phone by accident as there is no way back, if you succeed with erasing data with a magnet. Therefor, only use magnets on your hard disc or phone if you really want to delete data.
