Hello, I am trying to mount a dual layer dvd ISO image under PC-BSD 8.0 and am having some problems. I have been searching all night for answers and have found none. Here's what I've tried: Code: sudo mdconfig -a -t vnode -f myiso.iso (also tried with '-u 0' option added) it seems to associate the md device or whatever successfully, at least there are no error messages. then I try: Code: sudo mount -t cd9660 /dev/md0 /media/iso or Code: sudo mount_cd9660 /dev/md0 /media/iso they both give me the save error message: Code: mount_cd9660: /dev/md0: Invalid argument I also tried this, as root: Code: mount_cd9660 -o ro /dev/`mdconfig -a -t vnode -f myiso.iso` /media/iso but still the same error message. can anyone please help me with this or point me in the direction of some information that might help? Or does anyone know another way to mount isos? I dont have any blank dual layer dvds, so i cant burn the image to dvd. any help would be much appreciated. thanks in advance!
