Data Killer turns hard drives into blank slates with the push of a button (video)
Let's say you're embroiled in an international tale of espionage and intrigue, and you've got hard drives filled with incriminating evidence and top secret information. You could dispose of that potentially dangerous data by manually wiping each disk with multiple passes of a disk erasing app or, you could pop them in the Data Killer and be done with it in seconds. Platform of Japan demonstrated the information obliterating devices at the Information Security Expo. A large powerful magnet realigns the bits on the surface of the drive's platters eliminating all trace of the data that existed before, without physically damaging the hardware. With just the push of a button a Data Killer can wipe practically any magnetic media, including tapes or an aging floppy disk. The data disposals even come in different sizes, allowing you to kill just a single 3.5-inch disk or up to 14 at a time. The larger models can even accept an intact laptop. Check out the video after the break to see it in action.
Permanent Eraser 2.3.3
Should Auld Acquaintance be deleted... then too bad! Especially if you are using Edenwaith's free Permanent Eraser product. Unlike Disk Utility (and Mac OS X's secure empty trash), this disk eraser will over-write data 35 times (versus secure empty trash's 7 times). What many users don't know is that when you delete a file from your computer, it's not really deleted; the operating system just marks that space as "free." However, this software will over-write the area of the hard drive where the data remains until it is scrambled and unable to be read.This software received a new update yesterday that improves a bug that limited you to deleting 250 files. This application also has full Mac OS X Leopard support; including new icons for Leopard. In addition to deleting files in the trash can, you can also drag files to the icon to securely delete them. This application can be downloaded for free from the Edenwaith website or from Mac Update.[via Mac Update]
