How To Securely Store Data

Note : You require knowledge about file recovery to understand this article. In case, you have no knowledge about this, I highly recommend checking out my article on file recovery.

In one of my earlier posts I demonstrated File Recovery using Forensic Tools.
While File Recovery is possible if the file is deleted using Shift-Delete or even if the partition is formated.

This becomes a major security issue if your pendrive held confidential data earlier. Even quick format is not an option.

Using specialized tools forensic experts can manage to recover any data which was stored on pendrive or any other storage device, provided it is not overwritten. In case , it is overwritten the data could still be partially recovered. I had once recovered partially, a few images using Recuva. They don't look like the exact image but just the thumbnails can be pretty informative.
