Device
Fault bit: If the device enters a condition where
continued operation may affect user data integrity (e.g., failure to spin-up without
error, or no spares remaining for reallocation), then the device shall set the
Device Fault bit to one and no longer accept commands. This condition is only
cleared by power cycling the device. Once the Device Fault bit has been cleared
to zero it may remain clear until a command that affects user data integrity is
received by the device.
Error
bit: The Error bit shall be set to one if any bit
in the Error field is set to one.
