I was thinking of something different though. What if I want to keep my hard drives for now but make sure that deleted data can’t be recovered by any means ? I tried and ran some file recovery programs such as Recuva and it showed thousands of files that were still referenced on my system although they have been deleted before. I think that this is a privacy problem and decided to look for a way to delete all file information on the unused part of my hard drives.

I decided to use Recuva first and see how many file information it would find. After that I would run a program named Eraser which I will use to clean the unused disk space of any deleted file information and finally run Recuva again to see if this reduced the amount of files that could be undeleted from my system.

Testing my Hard Drive with Recuva:

Recuva found 33720 files on my hard drive f: that could be undeleted. This is a large amount of files.

Running Eraser:

After right-clicking the central pane I was able to create a new task. The first option was unused space on drive which is the default option in the menu. I selected the f: hard drive from the list. Eraser was showing my newly selected task in the central pane and I had to right-click that task once again and select Run from the context menu. It took two and a half hours to overwrite all the data on my 100 gigabyte hard drive.

Testing the result with Recuva:

Recuva found one file on drive f: Everything else was not found anymore which leads to the conclusion that this is an excellent way to erase file information that exists on the unused space on your hard drives. This is probably not enough to erase it for the big boys if you know what I mean but every amateur should have problems getting information about those files.
