Except that the majority of CD writers today are NOT SCSI devices. They may use the MMC command set from SCSI for interface purposes, but they are on an ATA or USB bus. cdrecord tries to fabricate some kind of device numbering assigning SCSI-like bus and LUN numbers for the devices when such a numbering has no basis in any kind of reality. We have all SCSI devices in a single namespace, that is what /dev is for. That is the name that the system/kernel provides for applications to use, and that is what the application should use, not some kind of bizarre invented numbering scheme built on top of that. -- Robert Hancock Saskatoon, SK, Canada To email, remove "nospam" from hancockr@nospamshaw.ca Home Page: http://www.roberthancock.com/
