Following on from yesterday’s post<\/a> I briefly outlined a problem that I was having with my LG GGW-H20L Super-Multi Blu-ray drive<\/a> burning to a Shintaro single layer BD-R (Blu-ray disc recordable).<\/p>\n\n\n\n

In a nutshell, it seemed that my burner did not know how to handle the Shintaro BD-R discs when it came to burning so I thought I’d have a go at seeing if I could fix this myself after my attempt to upgrade my burner to the latest firmware (being YL07 at the time of writing) didn’t fix the problem<\/p>\n\n\n\n

First up, I had to get the media identiciation code of the Shintaro BD-R I was using. I used an application called DVD Identifier<\/a> to do the job. It’s just a matter of popping in the blank disc, running the application and clicking the Identify<\/strong> button on the BD-R\/-RE tab.<\/p>\n\n\n\n

As we can see, there’s quite a bit of information there including burn speeds supported by the disc, number of layers, capacity and type. However, the details in which I was most interested were the Manufacturer ID<\/strong> (“CMCMAG”) and Media Type ID<\/strong> (“BA5”). We’ll see why later on.<\/p>\n\n\n\n

The next step was to extract the firmware from my burner so I could examine its contents. Sounds scary and perhaps rightly so for people who don’t normally poke around in the nether regions of device memory! The utility I used for this is called Flasher<\/a> (otherwise knows as Devilsclaw’s Flasher). There are versions available for:<\/p>\n\n\n\n
