Files deleted from the computer can be recovered if nothing else is saved in the same place. Therefore, the recommendation to have access to erased data without wanting to stop using the PC immediately. Removal software, such as DBAN, uses this feature to ensure that your information cannot be accessed. The solution basically consists of writing random data to storage, preventing the original files from being accessible again.

The cleaning mechanism varies. Depending on the user's need, it is possible to perform a faster procedure, which saves zeros and ones on the HD and checks three times before finalizing. Or it can be more time-consuming and effective, when the software writes a larger amount of random data and checks more often that none of the files can really be accessed with any recovery program.
