Math Calculations

One final area extremely pertinent to data recovery is its opposite effect. That is not the need to recover deleted files, but the need to make sure that once a file is deleted it is removed from our computer’s hard drive or other digital storage in such a manner that it can never be again accessed. There are programs created specifically to erase data. These are a byproduct of a reverse engineering of data recovery software. Often referred to as a data eraser or disk wipe program, this software overwrites the space allocated to a deleted file numerous times with scrambled information. So, even though this program might be considered a file eraser the process of erasing data from digital storage is nonexistent. The better and more common name applied to the process and the software is that of a file shredder. Powerful file shredding software tears down the original stored data to its fundamental machine code then rewrites that information on to the space allocated as empty and deletes files many times in a random pattern. This ensures that no person or machine can ever open the information again.
