How mucch do you Know?
When you delete a file to the recycle bin and then empty the recycle bin do you think that your data has been deleted from your system. ? If you think so then you should be reading what is written below.
That data you think you erased is still stored on the drive. When you delete a file it isn’t really removed from the disk. only the reference to the file from the file allocation table (FAT) is removed. This is like removing the table of contents from a textbook the actual chapter still remains in the textbook.
Even if you reformat the harddisk, then too the data remains and for people who are into computers it is a easy job to get the data which has not yet been overwritten from a formatted harddisk.
The only permanent way to make data irretrievable is to completely and utterly destroy the hard drive. But it is an action that is probably a little severe than required. The only thing which has to be done is to make the data irrecoverable. That is to be as safe as possible, you must overwrite both slack space and free space. Also, the Windows swap file could contain private data that you wouldn’t want to have fall into the wrong hands.
