If the Change Partition (CP) bit is set, the drive first changes to the specified

partition, then attempts to locate before the specified logical block. (All addresses

are interpreted as logical.) A locate to Block 0 (in any partition) is treated like a

rewind (to BOP)and does not start a read-ahead. Depending on the exact sequence

of commands, LOCATE to Block 0 might or might not report a Blank Check error.

The DSC bit is reset (0) after this command is accepted and is set (1) when

completed. REQUEST SENSE can then be used to verify successful command

completion.
