Eraser Pro 2012
Most people have some data that they would rather not share with others -
Perhaps you have saved some of this information on your computer where it
is conveniently at your reach, but when the time comes to remove the data
from your hard disk, things get a bit more complicated and maintaining your
privacy is not as simple as it may have seemed at first.
Your first thought may be that when you 'delete' the file, the data is
gone. Not quite, when you delete a file, the operating system does not
really remove the file from the disk; it only removes the reference of the
file from the file system table. The file remains on the disk until another
file is created over it, and even after that, it might be possible to
recover data by studying the magnetic fields on the disk platter surface.
Before the file is overwritten, anyone can easily retrieve it with a disk
maintenance or an undelete utility.
There are several problems in secure file removal, mostly caused by the use
of write cache, construction of the hard disk and the use of data encoding.
These problems have been taken into consideration when Eraser was designed,
and because of this intuitive design and a simple user interface, you can
safely and easily erase private data from your hard drive.
