I had this under kernel 2.2 and the reasons was one of the following: The ide cdrom driver loded and grabed the cdwriter as an ide device and saw it as a cdrom. To prevent this from happening one puts a statment in lilo.conf like: append="hdc=ide-scsi" after the root=/dev/hd5 or what ever. If that allone did not work i used to do: modprobe ide-scsi before i ran cdrecord -scanbus. hth Willem On Mon, 21 Oct 2002, Martin McCormick wrote: > When I give the command > mkisofs -l -R -q /home/martin/dsp |cdrecord -dev=/dev/scd0 -dummy - > I get > > scsidev: '/dev/scd0' > devname: '/dev/scd0' > scsibus: -2 target: -2 lun: -2 > cdrecord: Read-only file system.
