Will a Demagnetizer erase a hard drive?

Objects that are magnetized will remain that way until you demagnetize, or degauss it. … However, degaussing is not entirely fool-proof. It can only be used on magnetic media, and there is no way to guarantee that a particular degaussing machine is strong enough to destroy all the data on every hard drive.

Can data be recovered after degaussing?

Yes, degaussing is permanent. Data stored on a degaussed drive is irrevocably destroyed and has no hope of return or recovery.

  1. soak them in acid.
  2. scratch them all over with a screwdriver.
  3. sandblast them.
