Reading Blu-ray Disks

I was able to burn a blu-ray disk using Nero Linux. I verified that the information was written to the disk by opening it with a Windows machine, but unfortunately for backup restore purposes the Windows route will not be a simple one; the best solution is to be able to extract the data using openSUSE, since the data is composed it tar and bz2 files.

Under my computer, the disk shows up as "Blank BD-R" but when I click on it, I receive the message, "Method "Mount" with signature "ssas" on interface "org.freedesktop.Hal.Device.Volume" doesn't exist.

Here are some of the things that I have done so far:

Please let me know if you can assist. ANY direction/assitance/idea would be useful, helpful, appreciated...

Thanks,

Rafael.

you need UDF 2.5
this would require patching kernel. There is a lot of confusion regarding Blu-Ray (read only vs read/write support). You can check if upcoming opensuse 11 will support udf 2.5 and blu-ray

sorry

Broch,

Thanks, appreciate the reply. Is there a way to apply a patch and recompile the kernel, or is it just not supported at this point? Is there any other way, such as third party products where I can read the burnt info and extract it from the BD-R using SUSE? Or am I pretty much s.o.l. until the next SUSE release?

Thanks again,

Rafael.

you can apply patch against vanilla sources (currently 2.6.25.4):
www.kernel.org
in the howto section you will find a guide to patching and compiling custom kernel.
I don't have enough information regarding blu-ray and udf 2.5
You can probably apply patch cleanly but I don't have any information regarding functionality.

Unfortunately, without patched kernel, you may not be able to read/write blu-ray disks. I think that movies can be copied to the hard drive and latest mplayer should be able to read/play blu-ray (after decryption). This however you would have to check at
http://www.mplayerhq.hu/

http://sourceforge.net/tracker/?grou...95&atid=300295

download the patch that corresponds to your kernel version

I am not sure about other options that you would have to enable (or not) to make blu ray work

Brock,

Thank you, I will check out the information you provided me.

I really appreciate it, thanks!
