Abstract
An encryption-decryption disk drive arrangement has a recordable disk and is configured so that data can be securely stored on the disk. The drive housing or enclosure is sealed, and any attempt to open the housing or to access the internal electronics will cause the encryption/decryption keys and firmware to be erased from EEPROMs in the drive. The drive can be configured so that data are encrypted and distributed between two disks, which can be a writeable CD ROM disk and a magnetic disk. With this disk drive arrangement, the encryption and decryption operations take place in the drive, and do not affect the motherboard or daughterboards of the associated computer. This arrangement can also be used to authenticating or verifying digitally stored documents and records.
