(2) power off the drive on and reboot system -- After system is up, then power on the USB CD-RW drive and run command -- cdrecord -scanbus it shows that the drive is at SCSI 1,0,0 run command -- cdrecord -v dev=1,0,0 image.iso # ls bus error # halt bus error # shutdown -h now bus error # some command may work >How-To-Repeat: I do not have other USB drive, so I cannot tell if this is DRX-510UL specific.
