| Active KillDisk Professional.
|
| Active@ KILLDISK has several methods for data destruction that conform
| to
| US Department of Defense clearing and sanitizing standard DoD 5220.22-M,
| German VSITR, Russian GOST p50739-95.
|
| More sophisticated methods like Gutmann's or User Defined methods are
| available as well. You can be sure that once you wipe a disk with
| Active@ KILLDISK, sensitive information is destroyed forever.
| Active@ KILLDISK is a quality security application that destroys data
| permanently
| from any computer that can be started using a DOS floppy disk. Access to
| the
| drive's data is made on the physical level via the Basic Input-Output
| Subsystem (BIOS), bypassing the operating systems logical drive
| structure
| organization. Regardless of the operating system, file systems or type
| of
| machine, this utility can destroy all data on all storage devices. Thus
| it
| does not matter operating systems and file systems located on the
| machine,
| it can be DOS, Windows 95/98/ME, Windows NT/2000/XP, Linux, Unix for PC.
|
|
| Erase methods
|
| Erase method allows to define security level or cleaning standard for
| the
| following erase operation.
|
| It is one of:
| - One pass zeros: 1 pass, quick, low security
| - One pass random: 1 pass, quick, low security
| - US DoD 5220.22-M: 3 passes, slow, high security
| - German VSITR: 7 passes, slow, high security
| - Russian GOST p50739-95: 5 passes, slow, high security
| - Gutmann: 35 passes, very slow, highest security
| - User Defined: You can specify number of passes (random)
| 1 to 99
