Figure 114. Security Unlock information

Identifier A zero indicates that the device regards Password as the User Password. A one

indicates that the device regards Password as the Master Password.

The user can detect if the attempt to unlock the device has failed due to a mismatched password since

this is the only reason that an abort error will be returned by the drive AFTER the password information

has been sent to the device. If an abort error is returned by the device BEFORE the password data has

been sent to the drive, then another problem exists.
