Note a: The logical position is located on the EOM side of the mark if the movement was in the forward direction and on the BOM side of the mark if movement was in the reverse direction.
Note b: The Information field in the Sense Data is set to the difference (residue) between the requested count and the actual number of blocks, Filemarks, Setmarks, or spaced over.
Note c: The Information field in the Sense Data will contain no residue count and therefore the Valid bit is not set.
Note d: If it has been configured through MODE SELECT to Report Setmarks, the drive will only report that a Setmark has been detected while spacing over blocks or Filemarks. Otherwise, the drive will continue the space operation and the presence of the Setmark will be transparent to the nitiator.
Note e: The tape is physically positioned at BOM/P.
Note f: EOM is only reported when the physical EOM/P is encountered. The tape is physically positioned at EOM/P.
