CBL Data Shredder will allow you to shred data stored on your hard drive making it impossible to be recovered.You may think that you have removed data from the hard drive using conventional methods, but those files you thought had been deleted years previously, containing personal details, bank account information, credit card numbers, stored passwords, etc., are still there in some form and can be recovered relatively easily. Merely formatting the drive is not enough to keep that data safe from being accessed by a motivated interloper.CBL Data Shredder will erase the entire contents of a target hard drive ensuring that the data is irretrievable to existing recovery software. You have the choice of six different shredding methods, Custom Hard Drive Erase Method, DoD Standard 5220.22-M, Germany BSI Verschlusssachen-IT-Richtlinien (VSITR) Standard, Schneier's Algorithm, Gutmann's Algorithm, and the RCMP DSX Method. You can also select up to 35 overwrite passes if you like.We have included three author download links (with the MajorGeeks download being for Windows) they are for Windows, DOS (bootable floppy disk maker), and ISO (CD-ROM ISO for burning a bootable CD or USB flash drive).
