Complete erasure of a file from the hard drive
Many of us are of the false belief, that when we delete a file from the Recycle Bin, we have got rid of the file permanently. Although we are not able to view the deleted file, in reality it still exists on the hard drive, and is very much recoverable using data recovery software. This becomes a threat, if you are planning to sell your PC, or dispose your PC.
Anyone who gets to access your PC might well be able to recover the data you have deleted, from your PC using a data recovery software. This might lead to misuse of all your personal data present if any, on the hard drive. To ensure that your data is erased permanently from the hard drive, the disk space occupied by the deleted file, has to be overwritten at least three times with some junk values.
This requires a good data shredder software, which erases the data beyond recovery rendering it irrecoverable. REMO Shredder lets you do this easily with a few mouse clicks. This data shredder 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.
