Thanks. bdsf 126 54000 6000 :2.3G", # Exabyte 8200 bdsf 126 54000 13000 :5.2G", # Exabyte 8500 (double density 112m) bdsf 126 54000 18000 :7.0G", # Exabyte 8500 (double density 160m) bdsf 126 108000 13000 :10.4G", # Exabyte 8500-Compression 112m bdsf 126 108000 18000 :14.0G", # Exabyte 8500-Compression 160m these "work" for me, but I'm not sure if they're correct or not.
