Abstract: An electronic data security apparatus for providing adequate protection against adverse external conditions. The apparatus includes an enclosure having a connector interface, an internal control unit contained within the enclosure, data storage devices contained within the enclosure connected to the internal control unit, and an external control unit connected to the internal control unit. The apparatus is capable of sensing adverse external conditions such as fire, water and theft and secure the data storage devices by automatically disconnecting from the external control unit, closing and locking itself off from the outside environment thereby to protect the data storage devices from memory loss.
