Permanent Eraser 2.6.2 :: Securely erase your files
Permanent Eraser screenshot When you normally delete your files in Mac OS X, the operating system is only forgetting where those particular files are placed, while the data still physically remains on the drive. Beginning with Mac OS 10.3, Apple enhanced its security by introducing the Secure Empty Trash feature, which follows the U.S. DoD pattern of overwriting data seven times.

Permanent Eraser provides an even stronger level of security by implementing the Gutmann Method. This utility overwrites your data thirty-five times, scrambles the original file name, and truncates the file size to nothing before Permanent Eraser finally unlinks it from the system. Once your data has been erased, it can no longer be read through traditional means.
CD/DVD Erasing
Permanent Eraser fills in what the Finder forgot! Simply drag a CD-RW or DVD-RW onto Permanent Eraser to erase the disc's contents.
Automator + Services
Mac OS 10.4+ users get to make use of the bonus Automator Actions and Finder plug-in built to work with Permanent Eraser. Right-click on items you want to destroy and select Automator → Permanent Eraser, or make use of the Erase Trash and Erase Selected Items Automator Actions. Snow Leopard and Lion users get to make use of the new contextual Service menu to easily erase a file.
Universal Binary
Starting at Version 2.2, Permanent Eraser runs natively on both PowerPC and Intel-based Macintosh computers.
