Some time ago, I had a Western Digital hard drive I no longer needed. I took the drive and put in an industrial magnetic field generating machine. The magnetic fields generated by this machine are very strong! So strong, that if you are holding a metal bolt in your hand inside the coil, it will pull your hand to the center of the coil. I zapped the drive with max power, using AC and DC fields. I was sure the drive would be clean and probably would not work at all. But to my surprise, when I re-installed the drive, Not only did the drive still work, but I was able to access both programs and data. Everything was still there and still working. What could have shielded the platters from magnetic fields that strong?
