The disk drive is not in a state where it can be accessed.
An irrecoverable error was detected due to a defect in the disk media or an error in
the recorded data.
The HDD detected an error in the hardware for which recovery processing is impossible
during command execution or self-diagnosis.
An illegal value was detected in the parameter transferred in the CDB or the
specification in the command. Also, an error in the LUN specification. If the
HDD detects an illegal parameter in the CDB, it terminates the command without
changing the contents of the disk media. If an illegal parameter is detected in the
parameters transferred from the INIT, the contents of the disk media may be
changed by that command.
A UNIT ATTENTION condition occurred.
1) An illegal operation was attempted in an area where a read or write operation is
