TOC Type: 1 = CD-ROM scsidev: '1,0,0' scsibus: 1 target: 0 lun: 0 /usr/bin/cdrecord: Success. Cannot open SCSI driver. /usr/bin/cdrecord: For possible targets try 'cdrecord -scanbus'. /usr/bin/cdrecord: For possible transport specifiers try 'cdrecord dev=help'. Expected results: Burns the CDs. Additional info: This is a IDE drive installed as hdc1.
Try: $ sudo cdrecord -v dev=/dev/hdc1 cdrom.iso
First note a typo in the original description. The CD burner is installed as /dev/hdc rather than /dev/hdc1. The command "sudo cdrecord -v dev=/dev/hdc cdrom.iso" works correctly. If /etc/cdrecord.conf is modified to contain the line "CDR_DEVICE=/dev/hdc" rather than "CDR_DEVICE=1,0,0", then the simpler command "sudo cdrecord -v cdrom.iso" also works correctly. The man page for cdrecord still needs to be modified to suggest that these options are permissible (and now preferred, perhaps).
