There are various ways of getting rid of data on your hard drive. This involves both physical and logical methods of permanent erasure of data from your hard drive. Physical methods of data erasure include Degaussing, which is a method by which the magnetic field of a hard drive is reduced or destroyed, thereby making the hard drive unreadable. This is a good method of data erasure, but it results in a damaged hard drive, which cannot be used further for data storage.

But in case of logical data erasure, not only is there an assurance of complete data erasure, but there is also no physical damage that is done to the hard drive. This has made logical data erasure software a much sought after tool in today’s new age computing world.

Logical data erasure can again be done in two ways namely, by getting rid of files one at a time, or performing an erasure of the entire hard disk. In case you want to get rid of only a limited number of files, it is always better to make use of REMO Shredder software. If you want to completely erase your hard drive at one go, it is suggested that you make use of REMO Data Sanitizer for erasure of data. This data erasure software makes use of nine different sanitization standards for permanently wiping data from hard drive.

When you erase a file on your computer, the actual data in the file is not overwritten. The space utilized by that file is simply marked as “free” for use by other data. Once other data is written in that space, the original data becomes unrecoverable. Those little bits of magnetic media that store 0′s and 1′s are a bit more complex, however, and recovery of data becomes impossible, after the hard drive has been overwritten.

The method to securely erase data is to write over the same physical spot on the hard disk multiple times with different patterns, effectively obliterating the magnetic signatures of the data which was once there. This can be made possible by the use of a good data shredding software.

REMO Shredder software makes use of a powerful shredding algorithm to erase data from the hard drive. The software makes use of several military and government approved shredding patterns to shred data. The software also lets you shred free space from the hard drive.

While some users prefer to just take a backup of their data, on a daily basis, others go a step further to permanently delete files from their PC, after a complete backup has been taken by them. This is useful in cases where confidential data is involved, or at places where chances of data misuse is potentially high. There exists another method in which you can protect your confidential data. This is by scheduling a complete erasure task, at system start-up. In this way, permanently delete files from your hard drive, every time you restart your PC.

REMO Shredder lets you do this easily with a few mouse clicks. The software lets you schedule shredding tasks on particular date, at a particular time. REMO Shredder 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.
