How strong has the magnet got to be? How is the strength measured?

Is this a hypothetical question or do you want to know how to COMPLETELY remove all your data from a hard disk??
If it's the latter, use this:
It's way better than any magnet!!!

Magnetic strength is measured by "Tesla"
If a magnet rolls over a hard drive, it could or can not wipe out an area of the drive. Drives are encased in an aluminum case. If you want to wipe information, this is not the best method. If you have accidentally moved a magnet to a hard drive, "some" of the data may have been erased, but not all.

Yes, data is stored in 0's and 1's by using magnets to magnetize segments on the hard drive. Changing the polarization of many segments could leave your hard drive unrepairable. If you had a strong enough magnet you would damage the hard drive beyond repair.

You bet ya. Magnets should never be around a computer. I have seen a small magnet wipe a hard drive. I use to work for Maxtor and we did experiments. So yes they sure can.

Yes.
To remove all trace so that forensic techniques cannot recover data you need a field somewhere between 0.5 and 1.0 Tesla.

Not sure. But you can do that using Derik's Boot n Nuke
