SEEK (X’70’ to X’7F’)
This command performs a seek operation to the track and selects the head
specified in the command block registers. After completing the seek operation,
the device reports the status to the host system.
In the LBA mode, this command performs the seek operation to the cylinder and
head position in which the sector is specified.
•
