Bitsetting for LG GSA-41XXB drives
Hi all,
I've made a patch to dvd+rw-booktype to allow bitsetting on LG DVDRAM
GSA-4163B, and possibly 4120B and/or 4160B. You can get the patch from
http://www.sci.fi/~syrjala/dvd/
I got the details from the Windows bitset tool
http://www-user.tu-chemnitz.de/~noe/Bitsetting/
I've only tested it on my 4163B (firmware A102 and A103). I don't know if
it will work on 4120B or 4160B since I could not find any definitive
information about their bitsetting capabilities. The Windows tool's source
code has some firmware version checks for those drives but I didn't put
them in my patch.
You can change booktype for DVD+R or DVD+R DL discs. For DVD+R discs you
can choose DVD+R or DVD-ROM booktype and for DL discs you can choose DVD+R
DL or DVD-ROM booktype. Those restrictions were present in the Windows
utility source. I haven't tested what will happen if you try to tell the
drive to use some other booktype. Unfortunately you can't change the
booktype for DVD+RW discs.
If you try it on Linux 2.6 you need to be root since the SCSI command
filter won't allow unknown commands from normal users.
I sent the patch to Andy Polyakov so hopefully it will be included in the
next version of dvd+rw-tools.
