About disk wiping technology

Disk Drive is a device that stores digital data. Those data is stored on a surface of magnetic platters that rotates at a very high speeds. The magnetic property on a surface of a disk platter can be read or changed to either 1's or 0's. The entire information structure with all data on disk drive comes down to a large number of ones and zeros - the basic cell's of binary data. When you write a data on your disk drive (text, zip file, movie, whatever..) a row of 0's and 1's are written. That is your data. Now, when you delete the data those ones and zeros aren't deleted, merely a pointer to that data is being removed. That makes recovering such deleted data very easy.

Ok, what about formatting? Unfortunately, formatting a disk drive can not help securing the permanent deletion either. Formatting a disk drive does not actually overwrite the data, and although it is way better than deleting the file from within Windows it is still very easy to retrieve data back from a formatted disk.

The only real, and many times proven method of permanent data removal (without making a physical damage to a disk) is DISK WIPING technology. So, what is disk wiping and how it works? In order to permanently wipe a data from a disk all binary data, down to a basic 0's and 1's must be overwritten with a new data. So, contrary to what is's name implies disk wiping (or disk wipe method) doesn't really wipe, or delete the disk data, it actually replaces or overwrites the existing data with a new data. In it's simplest form the new data written could be all zero's, but more advanced algorithms use a combination of filling up a disk with random information plus multiple passes to ensure impossibility of retrieval from a wiped disk.

Disk Wipe is a free software that does so, it wipes the disk using one of predefined advanced algorithms, by overwriting the existing disk data with a new, random meaningless data, and it does so multiple times, by users choice, to secure even higher level of safety.
