Diagnostic code
(17) FORMAT TRACK (X'50')
Upon receipt of this command, the device sets the DRQ bit and waits the completion of 512-
byte format parameter transfer from the host system. After completion of transfer, the device
clears the DRQ bits, sets the BSY bit. However the device does not perform format operation,
but the drive clears the BSY bit and generates an interrupt soon. When the command
execution completes, the device clears the BSY bit and generates an interrupt.
The drive supports this command for keep the compatibility with previous drive only.
