ccleaner drive wiper

  ccleaner drive wiper

• ·          CCleaner includes a Drive Wiper, allowing you to wipe the free areas of your hard drive so that deleted files can never be recovered.

  When you delete a file, Windows removes the reference to that file, but doesn't delete the actual data that made up the file on your hard drive. This means that given the right software, someone could reconstruct all, or parts of files that you've deleted.

  
  

  ·         When you delete a file, it is only removed from the drive's "index," and the space is marked as "free" for future use.  The raw data remains in fragments on the drive until naturally overwritten.  That orphaned data can be extracted with specialized tools.

  problem with permanently wiping files & traces

  
  

  
  

  ·         I have some old files (mostly emails) I want to get rid of so that they are gone for good and not recoverable. These are files that I have deleted in the past non-securely by simply deleting them from windows. As they were deleted the old fashioned way, I ran Ccleaner to wipe free disk space, assuming it would get rid of them. However, when I use software like Recuva, I'm able to find and recover those files even after an MFT free space wipe with Ccleaner.
  
  Recuva shows these files as unrecoverable and I can see that they have been previously overwritten by other files. The files that have overwritten these seem to mostly be newer e-mail files or random windows files, so I assume this is done by windows when the disk space is needed.
