A common method used to counter data remanence is to overwrite the storage medium with new data. This is often called wiping or shredding of a file or disk. Because such methods can often be implemented in software alone, and may be able to selectively target only part of a medium, it is a popular, low-cost option for some applications. Overwriting is generally an acceptable method of clearing, as long as the media is writable and not damaged.

Some file eraser software make use of a simple overwrite technique, which writes the same data everywhere, often just a pattern of all zeros. At a minimum, this will prevent the data from being retrieved simply by reading from the medium again using standard system functions.

To counter more advanced data recovery techniques, specific overwrite patterns are often prescribed. These may be generic patterns intended to eradicate any trace signatures. For example, writing repeated, alternating patterns of ones and zeros may be more effective than zeros alone. Combinations of patterns are frequently specified. REMO Shredder is a powerful file eraser software, which provides nine different shredding methods, that exceed standards prescribed by various government and law enforcement agencies around the world.

There are large amounts of confidential and private data that are used in the IT sector. These personal and confidential data like credit card numbers and other classified data could get leaked and get into wrong hands and erase hard drive data permanently.

If proper erasure of data is not done, there is always a danger of  a user losing out all his private data, which will then be put to bad use by pranksters, or some other users who want to have a sneak peek at your data.

Due to the adverse situations cited above, it is now a necessity to make use of a shredding software, to get rid of all the data on the hard drive, including data that has been deleted. REMO Shredder lets you erase hard drive data permanently, with a few mouse clicks. The software lets you choose between nine different shredding methods based on different security levels. The software also lets you shred free space, by completely erasing even the deleted data from the drive.
