I got the above error with the command: "cdio -v -f /dev/rcd1c tao obsd5-amd64.iso"
but there was no problem with: "cdrecord -v -speed=2 dev=/dev/rcd1c:@ obsd5-amd64.iso" The cd burner is connected via USB. Dmesg messages: umass0 at uhub0 port 2 configuration 1 interface 0 "Acer Peripherals product 0x6007" rev 2.00/1.00 addr 3 umass0: using ATAPI over Bulk-Only scsibus1 at umass0: 2 targets, initiator 0 cd1 at scsibus1 targ 1 lun 0: <ATAPI, CD-R/RW 32X10, W.AR> ATAPI 5/cdrom removable What was my error? Thanks Rod.
