This command executes a seek operation of the cylinder/track where the logical data block specified

The functions and operation of this command are the same as those of the Group 0 SEEK command
(Section 3.2.7), except that it is possible to specify 4-byte logical block addresses.

This command specifies the address range of logical data blocks on an ID which it is possible to
access by commands which follow this command and which are linked to it, and to specify the type
of operations which it is possible to execute. It is possible to issue this command once only in a
group of commands which are linked in a series.
Note:
The specifications in this command are valid only for a series of linked commands which follow
this command. When the link between the commands is cut, the specifications in this command
lose their validity.
The "Logical block address" field in the CDB specifies the logical block address which is the staring
point of the range where access is permitted. When an address in the User Space (X '00000000' or
higher) is specified in the "Logical block address" field, access to the User Space only is permitted in
linked commands which follow this command and CE space cannot be accessed. On the other hand,
if an address in CE space (X '80000000' or higher) is specified, access to CE space only is permitted
in linked commands which follow this command, and User Space cannot be accessed.
