Best Free Hard Drive Eraser

When you delete a file, it isn’t really removed from the disk. The file content remains on the disk until another file is written over it. Basically, the same thing happens when you re-format a hard drive.

To be as safe as possible, use the best free hard drive eraser to delete files, and overwrite, erase or wipe both the free space and slack space, also the Windows swap file (aka page file) that could contain private data and you wouldn’t want to have fallen into the wrong hands.
