A security module for a removable disk drive having a lockable hardware write protect feature for use with docking base. Additional features provided by the invention are an enclosure and electrical connection interface designed to reduce or eliminate radio frequency interference (RFI) and electromagnetic interference (EMI), a removal mechanism that provides for orderly powering down of a disk drive before removal of the security module from a docking base, and a module latching and lock mechanism that provides for positive, lockable securement of the module into a docking base. |

DETAILED DESCRIPTION The present invention provides a docking base and a removable disk drive module having a lockable hardware write protection feature.
The invention may be configured such that a low-voltage power supply and computer interface are situated within the docking base, or the power supply is situated within the removable module, or the power supply is external to the docking base and removable module.
The docking base may be configured to receive one or more removable modules, and dimensioned to fit removable modules of various sizes.
The removable modules may be dimensioned to fit disk drives of various sizes.
Additional features provided by the invention are (1) a lockable tamper-resistant drive module having an electrical connection interface designed to reduce or eliminate radio frequency interference (RFI) and electromagnetic interference (EMI), (2) a unique drive module removal mechanism that provides for orderly powering down of a disk drive before removal of the module from a docking base, (3) a unique drive module latching and lock mechanism that provide for positive, lockable securement of the module into a docking base; (4) a usage counter to indicate the number of insertion/removals of the removable module and/or power applications to the enclosed disk drive; and (5) an electronic encryption circuit in the docking base so that data written on the disk drive in a removable module can only be deciphered when that removable module is used in a base unit.
The invention permits complete removal of a disk drive module from its docking base for security purposes, data transport, and replacement.
The inventive removable module can be securely locked into a docking base, as well as locked into a write-protect mode or read-write mode such that the mode cannot be changed without a key or combination to the lock.
The ability to lock the removable module into a write-protect mode provides data security when the disk drive module is in use, without concern for accidental or negligent alteration or erasure of data
