How to wipe a hard drive in windows 10 by keeping no trace

When we are going to get rid of our old PC for any reason, whether it is to throw it away or to sell it second hand, it is essential to delete all the information contained on your hard drive to avoid possible consequences. Our computers contain all kinds of personal and economic information inside, and if you do not want this data to end up in the wrong hands, you must clean the hard drive so that there is no trace.

Most computer experts will recommend formatting, but it is not enough, because while it is true that formatting removes most of the information found on the hard drive, there are remains and traces that remain its interior. In fact, there are many companies today that offer all kinds of services in this regard.

This process is really complicated, since generating random data on a computer is something that a computer is relatively unprepared for. However, there are random number generators that will do this for us, and that combined with a hard drive removal program will completely remove any information contained in it. The most used are the Mersenne-Twister random number generator, and the Darik’s Boot and Nuke hard drive erase program. You can find more detailed information about these programs by browsing Google a bit.
