No, you can't mount a blank CD-R :}
eroaster is -IMHO- a load of crap :}
Try xcdroast, k3b if it needs to be graphical...
Gtoaster or gcombust ...
Or just go with
Code:
mkisofs -J -R <directory(ies)/file(s)> | cdrecord -eject -dev=1,0,0 -speed=<YOUR BURNERS SPEED> -
man mkisofs
man cdrecord
for more details :}
Cheers,
Tink
