Simple question (I posed it previously but probably wasn't clear)
I have a dual-layer dvd burner (Sony DVD RW DRU-720A) which I got to
replace my old dvd burner.
I can successfully burn single layer dvd's with no trouble on this
drive - and after testing it works fine under windows.
However every dual-layer dvd I've burned so far is now an expensive
coaster. I have reread the docs I can find, but don't see any
additional options for the dual-layer dvd's ...
If somebody could give me some help on this one I'd appreciate it.
Notes: same results (failure) with both mkisofs ... cdrecord and just
using k3b. Tried on both DVD-R DL and DVD+R DL.
cdrecord-2.01.1; kernel-2.6.12-1.1372_FC3; minimal system activity;
no underruns reported at all.
My normal script is simple (here's the stripped-down version):
#!/bin/sh
cd ${1}
mkisofs -o /<somewhere>/XXX.iso -R -f -T -v -A \
"XXX" -V "XXX" .
(mount and verify the iso image, then unmount it)
cdrecord --dev=/dev/hdc -v -dao speed=16 -data /<somewhere>XXX.iso
resulting single-layer dvd-r works fine. double not recognized and
won't mount on any drive (on several machines with differing OS's).
I presume I'm missing an option here some place, but haven't found it
yet... so someone please give me a clue if you can.
Thanks,
