cdrecord problem - Cannot open '/dev/pg*'
My Ricoh DVD/CDR combo has been happily burning off discs for over 2 years from my box, currently RH8. Last weekend I got to the last of a batch of fedora isos though and got the following -
cdrecord -v speed=4 dev=0,0 yarrow-i386-disc3.iso Cdrecord 2.0 (i686-pc-linux-gnu) Copyright (C) 1995-2002 J?rg Schilling TOC Type: 1 = CD-ROM scsidev: '0,0' scsibus: 0 target: 0 lun: 0 cdrecord: No such device. Cannot open '/dev/pg0'. Cannot open SCSI driver. cdrecord: For possible targets try 'cdrecord -scanbus'. Make sure you are root. cdrecord: For possible transport specifiers try 'cdrecord dev=help'. and cdrecord -scanbus returns the same message. Seems to read CDs fine, is there any other way of testing whether it is the hardware that has failed or not? |
I think i got the same problem last time , and it was the scsi generic ( sg ) being not loaded
try lsmod and see if sg is loaded. if not you can try modprobe sg |
Looks like the scsi emulation is not loaded.
you need to add this line to /etc/grub.conf: hdd=ide-scsi Here is an exaple on a RedHat system: To add scsi emulation #boot=/dev/hda default=1 timeout=10 splashimage=(hd0,0)/grub/splash.xpm.gz title Red Hat Linux (2.4.20-8) root (hd0,0) kernel /vmlinuz-2.4.20-8 ro hdd=ide-scsi root=LABEL=/ initrd /initrd-2.4.20-8.img then try the 'cdrecord -scanbus' command again |
Nah, I think it's a hardware problem, it's not working in a windows machine I put it in either :(
