SECUDRIVE Sanitizer Free prevents possible data loss or identity theft from
PC recycling or hard drive cleanup. With just a few clicks you can activate
the powerful sanitizing mechanisms, used by the US DOD and other government
organizations, on any type of storage devices including hard disks and USB
flash drives. The program also features deletion of the operating system and
handles bad sectors automatically by exempting them from the sanitizing
procedure. (in System Utilities)
