Securing the Hard Drive Securing the Hard Drive This section includes: ■ Selecting the Hard Drive Overwrite Security Option on page 4-11 ■ Selecting the Automatic Removal of Secure, Personal, and Proof Jobs Option on page 4-12 Selecting the Hard Drive Overwrite Security Option When a file is deleted from the printer's hard drive, only the file name is deleted; the data in the file remains on the hard drive, regardless of the operating system. An unauthorized person could, possibly, retrieve the data in the file that was deleted. Printers with a hard drive have a Hard Drive Overwrite Security option. This option overwrites the data stored on the hard drive of a file marked for deletion using DOD5200.28-M, a U.S. Department of Defense three-pass overwriting process: first with a pattern of 0's, next with a pattern of 1's, and finally with a random pattern of bits. This is done before the file's directory entry is removed and the storage space on the hard drive is marked as available for reuse. The random pattern of bits stays on the hard drive until it is overwritten by another file. By default, the Hard Drive Overwrite Security option is disabled.
