For whatever reason, the scsi tape driver isn't recognizing your drive correctly. It thinks it's a Exabyte drive. Looking at the output of 'mt densities', try this: mt -f /dev/nst0 setdensity 0x25 0x25 being the density code for DDS3. To make sure compression is off: mt -f /dev/nst0 compression 0 The error log message you saw may be due to the driver having the wrong density code. -- Joshua Baker-LePain Department of Biomedical Engineering Duke University
