To prevent leakage of information accumulated in the device is called "sanitation" in the technical term. It is possible for companies to do sanitization as well as themselves, but many companies will ask hard drive crushing services, computer leasing companies, recycling companies, etc.

In terms of data erasure, physical destruction of hard drives (HDD and SSD) is probably the most reliable method. A hard drive is made into a piece of metal by a machine called a crusher.

The next option is to drill a hole in the hard drive, but even with a hard drive with a hole open it is possible to retrieve some data if a persistent hacker takes much time and money.

Another method is to erase information using a very powerful magnet such as a hard drive or a floppy diskDemagnetizationThere is also something, making any data stored on the drive unrecoverable.

And the last way is to overwrite all the data stored on the hard drive. If you overwrite it over and over again, the data will be erased completely. In the research, it is said that data is deleted even once by overwriting, but usually it will be overwritten three times for business use.

It is Peter Jegou's job to explain data erasure to these companies, but it seems that there are not many people who have a head because they do not understand easily.
