Package: dvd+rw-tools
Version: 6.1-2
When trying to read or set the booktype for the unit on a Lite-On dvd
drive, the dvd+rw-booktype will always fail when the drive is empty.
>dvd+rw-booktype -inq -unit+r /dev/hdc
:-( BTC_FAh: no media mounted
It always fails with a BTC error - even though my drive is not a BTC, it
is a Lite-On. After debugging, it appears the the error code returned
by the empty Lite-On drive is the same as what is expected in the code
from an empty BTC drive. The source should not assume that this is a
BTC drive when this error code is read.
After applying the patch, I am able to set and read the booktype on my
Lite-On drive without having to load any media.
>dvd+rw-booktype -inq -unit+r /dev/hdc
Unit will brand DVD+plus media as DVD-ROM
I'm using kernel 2.6.15.8 testing GNU/Linux with libc6 2.3.6-3
Thanks,
Ronan
