Selling a computer or smartphone with a hard drive is risky, there are numerous examples of data of all sorts found on second-hand computers but if for some reason you really must do that understand first how to securely wipe all data from the hard drive, one cheap option is to encrypt the whole hard drive with Veracrypt and reinstall the operating system, encrypting your operating system and throwing away the keys can work as a data wiper, this way you won´t have to buy special wiping software.

	Whether current secure erase provides adequate safety is subject to debate. There are those that say that only foolproof erase is to physically destroy the disk so the platter can not be played. Crush it with a steamroller, etch the platter surface with acid, melt it into a lump with fire. Do you know where all your backups are?

	After casual use, erased files remain available to anyone with an inexpensive program. To clean your computer completely, all the free areas of the disk need to be erased multiple times. One erasure is not enough to make data unrecoverable. U.S. military standards require 10 passes. Software to do this is easy to find.		After casual use, erased files remain available to anyone with an inexpensive program. They are not actually erased; one character at the beginning that this is an erased file. To clean your computer completely, all the free areas of the disk need to be erased multiple times. One erasure is not enough to make data unrecoverable. U.S. military standards require 10 passes. Software to do this is easy to find.

	Don't forget to secure erase any backups of your data. If you have backup stored with an external service, such as a cloud server, secure erase may not be available. And unless you are using a [[VPN]], which you should be, your internet service provider has a record of every URL (Web site) you viafited.		Don't forget to secure erase any backups of your data.
