Try looking at the output of the id command. I have a sneaking suspicion that is that you dont have permission to read and write to your CD device. I dont want to hand out the answer to a good practice problem like this one, so here's your homework ;o) Check the permissions of the device representing your CD-RW drive and decide what you will have to do to give yourself access to the device. Hint: you shouldnt have to modify the permissions of the device itself. > as root: > > cdrecord -scanbus: > > NOTE: this version of cdrecord is an inofficial (modified) release of > cdrecord > and thus may have bugs that are not present in the original > version. > Please send bug reports and support requests to > <[EMAIL PROTECTED]>. > The original author should not be bothered with problems of this > version. > > Linux sg driver version: 3.1.25 > Using libscg version 'schily-0.8'. > scsibus0: > 0,0,0 0) 'LITE-ON ' 'LTR-32123S ' 'XS0R' Removable > CD-ROM > 0,1,0 1) * > 0,2,0 2) * > 0,3,0 3) * > 0,4,0 4) * > 0,5,0 5) * > 0,6,0 6) * > 0,7,0 7) * > > cdrecord -scanbus -dev=ATAPI: > > [?] > NOTE: this version of cdrecord is an inofficial (modified) release of > cdrecord > and thus may have bugs that are not present in the original > version. > Please send bug reports and support requests to > <[EMAIL PROTECTED]>. > The original author should not be bothered with problems of this > version. > > scsidev: 'ATAPI' > devname: 'ATAPI' > scsibus: -2 target: -2 lun: -2 > Warning: Using ATA Packet interface. > Warning: The related libscg interface code is in pre alpha. > Warning: There may be fatal problems. > cdrecord: ERROR: unknow subsystem (scd0) in (/dev/sr0) > Using libscg version 'schily-0.8'. > scsibus0: > 0,0,0 0) 'MT1316B ' 'BDV212B ' '0.43' Removable > CD-ROM > 0,1,0 1) * > 0,2,0 2) * > 0,3,0 3) * > 0,4,0 4) * > 0,5,0 5) * > 0,6,0 6) * > 0,7,0 7) * > > > > > What have you done to investigate the problem to date? > not much as my fstab entry was wrong, xcd-roast did detect it as a scsi > device, leading me to belive that my fstab entry was correct > I think you've got the wrong idea of what /etc/fstab is for.
