The SEEK (6) command performs a seek operation on the block specified by the logical block address.

After finishing the seek operation normally, the command reports GOOD or INTERMEDIATE GOOD status. If the command fails in the seek operation, it reports CHECK CONDITION status.

The SEEK command need not be used for READ or WRITE command operation because these types of commands include the seek function.
