Abstract
External data storage device queries the user for a password on at least the first attachment. The password is escrowed in encrypted form. If the user elects this option, the password is then passed to an encryption module which unlocks the encrypted file or partition and upon subsequent attachments of the external data storage device may automatically unlock the encrypted file or partition using the securely escrowed password. The escrow of the encrypted password is managed in an external storage device containing the encrypted file or partition.
