Question

I tried to burn HD movie using Toast 12 on my iMac 10.8.5. I burned two failed disks.

The first one I burned directly from Toast to my LG burner. When completed, I tried to play it back. The disk failed to be recognized.

The second time l created from Toast a Disk Image onto my hard drive. Then I selected "Copy" in Toast, found my Disk Image and burned to a second blu-ray disk. I received two error messages. The first, The driver Roported and error: Sense KEy=Medium Error, Sense Code= O x OC, Write Error. I selected OK and it continued to burn. Then the second error message, Mismatch at byte 1/sector 16. Verification failed. Now I have two bad disks.

As I am new to burning Blu-ray, I do not know if this is a hardware problem (new blu-ray burner from OWC at there recommendation), or a software problem (Toast 12 came with the burner). Or is this a blank disk problem?

Did the first disc fail to be recognized on your Blu-Ray player and on your Mac? If it mounts on the Mac using the Blu-Ray drive see if it can play using Roxio Video Player in the Toast Extras menu. Unfortunately burned Blu-ray Discs aren't always recognized by standalone players.

 

The second disc suggests defective media. However I am having trouble burning a second disc to my Blu-Ray drive using Toast unless I quit and reopen Toast between burns. If you relaunch Toast you may find that the image file burns without problem. It also may be playable. Give it one more try. You also might unplug and replug the Blu-Ray drive before launching Toast.

I just downloaded Toast Titanium a few days ago. I cannot burn larger file content (22GB) without getting the same error message as zieve (Sense KEy=Medium Error, Sense Code= O x OC, Write Error). I did get it to burn and play on a short 1GB test. I have read many of the threads with regard to bad media being the cause, the burner, making a disc image and burning from it, etc. I've tried every scenario without success on a project that has got to be delivered in a few days. I'm at wits end. I've been running tests, doing research and wasting time on this for 48 hours. I never dreamed that creating a Blu-ray DVD would be so difficult. What gives? Any advice would be very much appreciated.

 

I'm running:

TOAST v12.1

Mac OS 10.7.5

OWC LG Blu-ray Burner (via USB 3.0)

Verbatim BD-R 6x 25GB

I don't know what to suggest. The error is happening near the outer edge of the disc. It could be the media or it could be the burner or something else. Have you checked with OWC about whether a firmware update is available for that drive? If you can get ahold of a 50 GB Blu-ray disc that may work for you in this case. You also could take a disc image to someone who burns Blu-ray discs. I don't have a project that uses that much space but others have burned data Blu-ray discs full for spanning backups.

I appreciate your response. Well, in the end it was the media. Evidently Verbatim 6x stock doesn't work with the OWC (LG) Blu-ray burner very well. The Verbatim stock worked with small files, but not large ones. I used one of the discs that came with the OWC burner and it worked! (The stock they sent was Millenniata/MDBD003 - never heard of it)

 

Now I question if I ever had an issue with Adobe Encore. So many variables that it's difficult to nail down the issue. Anyway, I appreciate those on these forums who are willing to invest their time to share knowledge. It certainly speeds up the problem solving process.

It sounds like the drive came with some sample Blu-ray M-DISC media; it's "archival quality" media that's (literally) designed/expected to last 1,000 years (vs. the typical 20-30 year lifespan for well-cared for optical media). If you're not familiar with it, check out the mdisc.com web site. I'm currently involved in a "conversion/archiving" project to go back through all my own personal videos (including some which I currently don't have on disc), bring 'em "up to date", and make (at least) one M-DISC copy of each.
