You are probably going to have to repartition, reformat and reinstall everything on the hard drive. That's if you haven't also corrupted the hidden information put there by the manufacture. If you have, the drive is toast and the only way to resurrect it is a low level format, and a mean proper low level format, and only the manufacture has the ability to do that.

Strong magnets and magnetic storage media just do not go together.

Echoing Sturat S above; magents and magnetic media - and a hard-drive is just that... - don't mix well at all...

You say system won't recognise the drive anymore... Does it appear at least in the bios?

The way a computer recognizes a modern hard drive is with a small bit of memory region on the drive that reports to the system board. That memory region is usually burned on a chip and unlikely to be affected by a regular magnet.

I'd look at bios first and see if it can show the drive. Then I'd use hard drive diags to at least do some checks on the drive. If both pass then I'd see what it shows in Device manager. Might have to try unstoppable copier or similar if you can even mount the drive.

Why did it take me over a year to phone in a problem to ATT?
