LG Blu-ray Burner Can't Read LG BD-RE Disc It Recorded?

[BassPig]

I have an LG GGW-H20L Blu-ray Burner in my editing workstation, which I use to write BD-R/RE discs.

This evening, I was checking some of the BD-RE discs in my closet, seeing what is available to erase and reuse for testing a new title that I'm authoring.

One of the BD-RE's is the LG brand that came with the LG burner. Oddly, the burner cannot read that one disc! I am greated by "Windows cannot read from this disk. The disc might be corrupted, or it could be using a format that's not compatible with Windows."

The next thing I do is load this disc into my Sony BDP-S301. It plays as a Blu-ray movie disc and it's a concert I authored last year. So the disc IS good. Knowing that, I take it back over to the LG GGW-H20L Blu-ray Burner and load it a second time. After a long delay, the same error appears.

I also have a TDK brand BD-RE disc and the LG GGW-H20L Blu-ray Burner can read that just fine.

Is it a little odd that an LG burner cannot read a disc by the same brand (and that came with) as the burner?

Not particularly, a friend of mine had a DVD burner (interestingly also LG), that burned DVDs that could be read by anything _except_ that very same burner (I admit the media was probably something cheap, I don't remember).
I don't have much experience with that kind of thing, but you could look if there is a firmware update available, it is supposed to help sometimes...

LG does not manufacture any optical media; they are just rebranded. If I'm not mistaking it should have been Ritek.

"Play just fine" is not an issue here. Simply because some drives are more tolerant than others. It will then play fine on one drive and maybe not at all on another one.

Anyway, I assume the drive is still in warranty, so take it back to the shop.

>take it back to the shop.

But it could be a bad disc too--obvious thing to do is to try to rip it on another PC/BD drive (and if successful, burn again to another disc).

For sure that it seems to play OK on a SAP means little as they are often more tolerant of disk errors than PC drives.

I noticed that you said that you created the BD-RE, kept into a closed (probably watched on the Sony), then wanna read it back on PC. Windows refused it.

Windows XP and previous does not have by default an UDF2.50 driver, which should be installed in order that the content of the AVCHD/BD be seen. You can however burn such discs without having such a driver, it's no needed.

If you have no driver, then every AVCHD/BD disc will output such an error. A BD-ROM with data might also have an ISO structure in parallel which is readable by Windows by default.

How about that?

Hi!

I believe you overlooked the following statement in the OP's initial post:I also have a TDK brand BD-RE disc and the LG GGW-H20L Blu-ray Burner can read that just fine.

Interesting point about UDF 2.5. I don't know if I tinkered with the UDF settings in Nero when I burned that disc. It was just some test content that I was going to delete anyway. I had burned it last year and, before erasing it, wanted to know what was on the disc and that's when I found the PC couldn't read it.

I've since erased, burned new video onto it and can read it in the PC. I used 'automatic' UDF settings in Nero this time. Not sure if I did that last time, so can't rule out possibility that I may have done UDF 2.5 based on reading some forum post about compatibility with set top players. If that was the case, then your answer explains it.

Not sure who made the RE media that comes with the LG burner.

Another thing I noted about burned discs, even BD-R, is that they seem rather slow at reading back data. For instance, I can't play back camera footage without stutter and long pauses off a BD-R that I recorded, but I can play similar footage smoothly of the same format and bitrate off a DVD-R DL disc I burned in that writer. I was of the impression that BD-R had a faster read rate than DVD, but apparently not in the LG writer. The brand of media I was using in that instance was the low-cost Blaze discs that everyone seems to be raving about and which I have been testing for suitability. Those same discs play smoothly in set top players that I tested it on, including Samsung BD-P1600 and Sony BDP-S301.

There are still some mysteries to be solved, but overall, this Blu-ray technology is more positive than negative in terms of the benefits I perceive with use.
