I had always heard magnets will mess with computers, but what I've seen I don't agree totally. Tapes, floppy disks, etc. absolutely don't even put a magnet by them.
Many people say put them on your case you'll mess it up due to most hard disks being mechanical. I had an old HDD I didn't care about, I decided to try it. I used a 1KW 120V AC tape eraser. It had absolutely no effect on the drive.
I know many drives have fairly strong magnets in the actuator, so why aren't those erasing data, etc, on the drive. My only thought in both these cases is because the metal around the actuator magnets shields the force in the small area. And that the shell of an HDD is like a faraday cage, and no magnetism will go through.
Just wondering what people thought about this, or am I just not using large enough magnetism to effect a drive. Also any theory on how a magnet near the platters on an HDD will not effect the data on that platter.
