2. Of course, every security expert knows that a recommended way to remove a hard drive is a demagnetizer. It uses electronic phenomena to delete data. The National Security Agency in the United States has recommended how to delete this hard drive with the military and the government.
3. Another method is to embed your hard drive in the acid - clohyddric acid is the best. Please sink the hard drive into acid for about two hours and the metal will be corroded, making the device useless.
4. Obviously, the above method depends on you having time to wait for acid to corrode the hard drive, but in some cases speed is most important.
Individuals serving in the military and security who want to avoid the information falling into the wrong hands can cause the hard drive to explode. This should be remembered to be done remotely.
5. Donating old computers can be an option. Organizations like Computer Aid International will take your hard drive to use for charitable purposes. Data in the hard drive will be erased before installing new operating systems and applications.
