Receive Diagnostic Results - IBM Ultrium Internal Tape Drive T200 Reference Manual

The First Block Location and the Last Block Location are both set to the number of
blocks and file marks between BOM and current logical position. If the tape is at
BOM, 0 is returned in these fields. The Beginning of Partition (BOP) flag is set if the
Block Location fields are 0. The End of Partition flag is not supported and is set to
0. The Block Position Unknown flag is always set to 0, since the position is always
known. The Partition Number, Number of Blocks in Buffer, and Number of Bytes in
Buffer are not supported and are returned as 0.
