Part D: Marking Classified Storage Media
Classified storage media must be safeguarded as classified material and must be marked in
accordance with Chapter 4, AR 380-5. Computer storage media are a special category of classified
material as far as marking.
Basic Identification: As well as security markings, computer storage media require other
external labels. You can't tell what information is stored on a floppy disk by looking at it. Therefore,
it is recommended that all computer storage media have some form of basic external identification,
such as a label identifying, at a minimum, the disks contents and date. This procedure is not required
by AR 380-19, but it is recommended that storage media be identified with this basic information. The
best procedure is to use a label formatted in accordance with AR 25-400-2, The Modem Army
Recordkeepkig system (MARKS), similar to the following example:
XX Corps OPLAN 98-7
Organization and MARKS file number: The organization or unit which created or owns the
medium. The units designation or the units office symbol may be used (ABCD-EF).
Permanent ID number: A unique identification number or serial number assigned by the unit
ID title or name: A title which identifies the contents of the medium. This is alike a document title
(XX Corps OPLAN 98-7).
User The primary user is probably the individual who created the medium, and can be identified
by name or position (MSG Swendsen).
Date created: The date the medium was created (6 Jul 98).
