It's complaining about /dev/hdc not being a valid device (as far as cdrecord is comcerned). which kernel are you running? [stuart@behemoth stuart]$ uname -r 2.6.7-1.494.2.2 if it is 2.6.8 _downgrade_ to 2.6.7 or burn as root. noone else is able to with that kernel. > cdrecord comand: > ----------------------- > /usr/bin/cdrecord -v gracetime=2 dev=/dev/hdc speed=52 -dao > driveropts=burnfree -eject -data /home/thornton/media2.iso what does # cdrecord -scanbus dev=ATAPI give you?

KDE is misreporting the error. it can't mount it because you haven't actually burnt anything to it yet. You can mount _other_ CDS, right. the error stems from the cdrecord command above. ALthough you can use device names, I have always had more success with the original cdrecord syntax: If this is an IDE/ATAPI device this syntax is # cdrecord -v dev=ATAPI:0,0,0 -dao driveropts=burnfree speed=52 -eject -data thingy.iso in fact the command you issued can be shortened considerably: # cdrecord -v dev=ATAPI:0,0,0 -dao thingy.iso the speed will be determined automatically, as will -data (it's the default) in fact -dao could be left out too if you wish. the ATAPI:0,0,0 will depend entirely on the cdrecord -scanbus output once you know how cdrecord sees your device you can edit /etc/cdrecord.conf to match. One gotcha though, I had issues until I changed the ATA line in cdrecord.conf to ATAPI ---cdrecord.conf (edited) : # The default device, if not specified elswhere CDR_DEVICE=cdrom # # The default speed, if not specified elswhere #CDR_SPEED=40 # The default FIFO size if, not specified elswhere CDR_FIFOSIZE=4m # Unless you have a good reason, use speed == -1 and let # cdrecord use it's intercal drive specific defaults. # drive name device speed fifosize driveropts cdrom= ATAPI:0,0,0 -1 -1 burnfree ----- end cdrecord.conf HTH Stuart -- Stuart Sears RHCE, RHCX Quidquid latine dictum sit, altum viditur
