4.9.8 Medium Partition Page (11h)
The tape drive supports the Medium Partition Parameter Page, which has the following format:

Medium Partition Page — Data Format
Compression
Algorithm
The Compression Algorithm field indicates which compression algorithm the tape
drive uses to process data from the initiator when the DCE bit is 1. Specifying a
value other than 10h for this field causes the tape drive to return CHECK
CONDITION status with the Sense Key set to ILLEGAL REQUEST (05h).
However, if EEPROM parameter EnaRepDecomp is set, the parameter in this field
is ignored and the tape drive returns no CHECK CONDITION status.
Decompression
Algorithm
The Decompression Algorithm field indicates which decompression algorithm the
tape drive uses when decompressing data encountered on the medium. Specifying
a value other than 10h for this field causes the tape drive to return CHECK
CONDITION status with the Sense Key set to ILLEGAL REQUEST (05h).
