Wiping Confidential Data

1.2 Wiping Confidential Data from Unoccupied Drive Space

You may have confidential data on your hard drive in spaces where data may have been stored temporarily.

You may also have deleted files by conveniently using the recycle bin and then emptying the recycle bin. While you are still using your local hard drive, there may be confidential information available in these unoccupied drive spaces.

Wiping the logical drive's deleted data does not delete existing files and folders. It processes all unoccupied drive space so that data recovery of previously deleted files becomes impossible. Installed applications and existing data are not touched by this process.

When you wipe unoccupied drive space, the process is run either from DOS or drive is being locked under Windows before wiping starts. As a result, the process does not depend on Windows system caching and deleted Windows system records can be wiped clean.

KillDisk wipes unused data residue from file slack space, unused sectors, unused space in MTF records or root records.

Wiping drive space can take a long time, so perform this operation at a time when you are prepared to wait. For example, it is a process that can be run overnight.
