Abstract
A method for recovering a password includes: obtaining a request code from a data storage device, transmitting the request code to an external authority that produces a recovery code from the request code, and using the recovery code to recover a password and an encryption key from a hidden area of the data storage device. An apparatus that can be used to implement the method is also provided.
