How to erase a disk or completely erase data on a disk

For files deleted on your computer, normally, if you don't have a special deal, the system simply deletes the file name in the Files allocation table, and the real data is still on disk. With some data recovery software, it's easy to recover files that have been called deleted.

The partition assistant has the ability to erase the disk, it can completely delete the data on the disk, so that the data on the disk can not be erased or deleted by other data recovery software, which can achieve high data confidentiality. For example, you don't want to use an old disk that needs to be sold, yet worry about people seeing you deleted files or deleted pictures, movies, and so on. The partition assistant's Erase hard disk feature will become quite useful.

Erase disk data operation steps
