Abstract
On power-up, self-encrypting drives (SEDs, 150) are unlocked one after another in an order based on the SEDs' unlocking priorities. In determining the priorities, one or more of the following factors are taken into account: (1) the content stored on the SEDs; the SEDs storing the OS are given higher priorities; (2) the SEDs' access history on previous power-ups: if a SED was accessed earlier than other SEDs, then this SED is given a higher priority; (3) whether there is an access request pending for a SED. Such prioritization allows the system to reach full functionality faster on power-ups. Other features are also provided.
