RESOLUTION

Downgrading HP ProtectTools Drive Encryption while an HDD is already encrypted cannot be performed successully. Version 6.0.80 (and later) of the HP ProtectTools Drive Encryption software actually prevents the downgrade process from being initiated. However, versions that were released before 6.0.80 do not have this built-in safeguard and inadvertently allow the downgrade process to proceed on an already encrypted HDD, which subsequently results in this problem.

If an HDD has been downgraded to a version of HP ProtectTools Drive Encryption prior to 6.0.80, download the most recent version of the software and install it.

NOTE: It is highly recommended to back up your data before upgrading the Drive Encryption software.
