DLT2000 SCSI Interface
8-54 DLT2000/DLT2700 Cartridge Tape Subsystem
DDE (Data Decompression Enable)
When the DLT2000 reads compressed data from tape, it automatically decompresses
the data before sending it to the initiator. Data compression is always enabled, so this
bit must be set to 1 (enable data decompression).
RED (Report Exception on Decompression)
The DLT2000 does not report exceptions on decompression (boundaries between
compressed and uncompressed data). The RED field must be (00h).
Compression Algorithm
The Compression Algorithm field indicates which compression algorithm the DLT2000
will use to process data from the initiator when the DCE bit (byte 02, bit 7) is 1. The
only value currently supported for this field is 10h.
__________________________Note _____________________________
Specifying a value other than (10h) for this field causes the DLT2000 to
return Check Condition status with the sense key set to Illegal Request (5h).

Decompression Algorithm
The Decompression Algorithm field indicates which decompression algorithm the
DLT2000 will use when decompressing data encountered on the tape. The only value
currently supported for this field is (10h).
__________________________Note _____________________________
Specifying a value other than 10h for this field causes the DLT2000 to return
Check Condition status with the sense key set to Illegal Request (5h).
