My unit's firmware: library 05.03, tape d22h, shows the device as set to random mode. But mtx -f /dev/st0 status gives an error that google says the device is in sequential mode. dmesg|grep -i hp does reflect CentOS thinks the device is a sequential unit. I've tried this with Fedora 8, too, and both show the same, so it is either an issue with CentOS/Fedora RPMs, or the version of MTX? I'm going to try a simple install of Ubuntu next and see if there is any difference. Is this a bug with the firmware, or with my setup? I have rebooted the tape drive and machine several times. I have the drive connected to an Adaptec 29160. I have another identical drive on another system, with a library firmware of d21h, tape firmware 04.04, and that works perfectly with mtx, though it is connected to a different SCSI card. Thanks for any help/insights. Scott
