Spinpoint M8-DVR Disti Product Manual REV 2.0
If the NCQ command is executed with error, the drive will report the error information from the Read Log
Extended log page 10h. This is special log page for the NCQ command error reporting. The details of the error
information are defined in the SATA II specification.
When the commands of queue and non-queue are mixed, the Spinpoint M8 drive will report command error.
This will ensure the queue sequence is correctly received.
Two ATA commands are added for this NCQ support: Read FPD
MA Queued (60h)
Write FPDMA Queued (61h)
The Set Device Bits (SDB) FIS is also used for indicating the completed NCQ command(s). The bits in this
FIS signify the completed tag. This SDB FIS is used for reporting error when there is a problem read or write
to the disk.
