Take a look at this output from a DDS drive here: goblin:~ # tapeinfo -f /dev/sg4 Product Type: Tape Drive Vendor ID: 'HP ' Product ID: 'C1553A ' Revision: '9503' Attached Changer: No MinBlock:1 MaxBlock:16777215 SCSI ID: 5 SCSI LUN: 0 Ready: yes BufferedMode: yes Medium Type: Not Loaded Density Code: 0x24 BlockSize: 0 DataCompEnabled: yes DataCompCapable: yes DataDeCompEnabled: yes CompType: 0x20 DeCompType: 0x0 Block Position: 65075 DataCompEnabled is the key here, I think. CompType - Compression Type - is probably not important. I assume it'S some sort of an indicator to what algorithm is used, but as long as I can't change that I don't worry about it. DeComp means, as you guessed, decompression. So, in my example, you see a drive which currently uses compressed mode and will decompressed compressed data when it encounters some. I never had to worry about these details, though - once I learned that I could rely on the drive working correctly no intercation was necessary.
