Chris, I'm using a Certance DDS-4/DAT72 drive, which I believe is the same as yours, perhaps just a later model since all Seagate tape drives now are Certance. As you said, data compression is set with a DIP switch. Here's the output of tapeinfo -f /dev/sg0: Product Type: Tape Drive Vendor ID: 'SEAGATE ' Product ID: 'DAT DAT72-000' Revision: 'A030' Attached Changer: No SerialNumber: 'HV00D4Z' MinBlock:1 MaxBlock:16777215 SCSI ID: 6 SCSI LUN: 0 Ready: yes BufferedMode: yes Medium Type: 0x35 Density Code: 0x47 BlockSize: 0 DataCompEnabled: yes DataCompCapable: yes DataDeCompEnabled: yes CompType: 0x20 DeCompType: 0x20 BOP: yes Block Position: 0 which clearly shows data compression enabled and I routinely get something on the order of 60GB's of data per tape.
