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 BYS 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.

(18)READ LONG (X'22' or X'23')

This command operates similarly to the READ SECTOR(S) command except that the device transfers the data in the requested sector and the ECC bytes to the host system. The ECC error correction is not performed for this command. This command is used for checking ECC function by combining with the WRITE LONG command.
