Field Name Description
BT Block Type. The Block Type bit indicates how the
Block Address field is interpreted. The first
recorded object (block or filemark) is at address
0, and Block Addresses count both data blocks
and filemarks.
CP Change Partition. Since multiple partitions are
not supported, this bit must be set to 0.
Immed Immediate. If this bit is set to 1, status is returned
as soon as the operation is started. If set to 0,
status is returned after the operation has
completed.
Tech Tip: The immed bit is accepted, but ignored
in processing.
Block Address The Block Address field defines the SCSI Logical
Block Address to which the media will be
positioned. These addresses start at address 0
and include data blocks and filemarks. They
could also be considered an object address.
Partition Not applicable (see Change Partition field
above).
