Seek command (0Bh)

The Seek command (Table 162) requests that the drive seek to the specified logical block address.
For systems which support disconnection, the drive disconnects when a valid Seek command is received. The
use of this command is infrequent since all commands involving data transfer to/from the drive media contain
implied seek addresses.
