This isn't why it didn't work though: disks tolerate smooth magnetic field gradients just fine. To wipe them you want a chaotic, noisy electromagnet.

Basically it's the transition in field strength, not the field, which flips a bit. So you need a moving magnetic field, and you need to cause a lot of changes because HDDs have all sorts of error correction.
