Note: The lamps flash at a rate of about 1 Hz when a rebuild is
in progress, and at a rate of about 4 Hz when an error
has occurred on both drives.
During operation, the HDD status lamps sometimes flash for a brief moment. However, this does not
necessarily indicate that an error has occurred on a drive.
