A portable data storage device (1), sometimes referred to as a "pen drive", "thumb drive" or "USB key-ring storage", attaching securely to a key-ring (2) while carried by the user, or attaching securely to a computer-tethered security cable (5), such as that described in U.S. Pat. No. 6,305,197, when left unattended to deter theft. The portable storage device attaches to a security cable (5) without the need to unlock said security cable's lock (17). A physical key device (3) or (alpha) numeric key number for a combination lock (4) is used to release the portable storage device from the computer tethered security cable (5) or key-ring (2).
