Software to recover deleted data on hard drives and other media can be easily found on the internet these days; which is a good thing. For example, one of my favorites is Recuva (by Piriform), which is FREE… I recently used Recuva, to assist a relative, to recover deleted picture files that were accidentally deleted.
However, on the flip side of the coin there are occasions where you should take precautions to prevent deleted data from ever being recovered. For example, let’s say you are working on something that is sensitive in nature, contains private information (for your eyes only) and you decide to delete it from the computer’s hard drive or other media. In essence, even you if you dump the recycle bin following the deletion, there is a high probability that the file can still be recovered.
To have peace of mind, I recommend using an utility such as Blank And Secure to permanently delete those sensitive files.
Blank And Secure is different than many of the other wiping utilities that I have tried in that it will overwrite the file your desire to delete with zeros (up to 35 times). According to the developer, recovery of a deleted file is impossible after using this utility.
To use Blank and Secure (which is portable), simply download and run; drag/drop the file onto the program interface; select the number of times to overwrite/ then hit delete. If you are not into dragging and dropping, this program may not be for you; however, if you want to delete an important file, I truly believe the concept behind this program will permanently prevent it from being recovered.
Another feature of this program is that you can fill the free space on the drive with “null” (or zeros) to remove all deletion tracks on the drive. I would only use this option if you were going to give the computer away at the end of its’ life cycle and you want to make sure there is nothing lingering behind on the free space area of the drive.
