NC State University has a perpetual license for Active@ KillDisk Professional 2015, which is a configurable disk-cleaning utility designed to permanently remove data stored on Windows or Linux university-owned computer hard drives. This software will work regardless of the operating system installed on the machine (Windows, Linux, etc.). When used properly, Active@ KillDisk will remove all data on a hard disk without the possibility of future recovery.

1. Contact your local IT group to request a copy of the Killdisk.iso file. If your local IT does not have a copy, they will need to request it from the Vendor Risk and License Management (VRLM) office.
2. Mount the Killdisk .iso file to a bootable disk or USB drive. VRLM has instructions on how to make a bootable USB drive if you need assistance.
3. Boot the machine to be erased from the removable disk into a DOS environment.
4. From the DOS menu, select the action you want (for example, reviewing data contained on the hard disk, deleting data contained on a specific partition, or deleting all data on the hard disk).

Active@ KillDisk allows you to specify various levels of disk cleaning (for example, cleaning to established Department of Defense standards for the protection of critical data).
