When question about data security arises, deleting the files doesn’t ensure safety in any ways. It is still recoverable as the data still exists on the disk and if by chance it falls in wrong hands then your data is no more secured. High-quality Disk Eraser would help to delete file beyond recovery by overwriting the data several times based on the shredding method selected.
Remo File Shredder supports several methods of shredding data or free disk space that are based on security levels. In general, if the data is overwritten several times then the data recovery would be impossible.
It works on the same principle by overwriting the data or free disk space with selected method several times. If low security pattern is used to erase the data then there are chances that the recovery could be done by hardware specialists who can read off the disk and get the data back with a pattern of bits.
High security shredding methods are bit complicated. They overwrite the data with selected patterns several times that makes the data impossible to recover. Remo file shredder use powerful algorithms like NATO, NAVSO, Peter Guttmann etc. that overwrites the data several times. Once these methods are used to wipe data, then hardware recovery attempts also would fail.
Remo File Shredder utility provides nine shredding methods for erasing data:
- Fast Zero Overwrite
- Random Overwrite
- US Navy, NAVSO P-5239-26 – RLL
- US Department of Defense (DOD 5220.22-M)
- DOD Standard 5220.28 STD
- North Atlantic Treaty Organization – NATO standard
- Peter Gutmann Secure Deletion
- US Department of Defense (DoD 5220.22-M) + Gutmann Method
