The drive should be doing about 24MBps. The tape is a DELL 110T LTO2 which runs at about 86Gb/hr. I am trying to diagnose where my problems could lie, and was wondering how I could see if there are any errors in the communication between the tape and the scsi card (320Mbps). I'm quite confident the speed issue is related to the tape drive or the scsi chain. Your suggestions welcomed. JB
