burnitgood

you're right, I just got lucky. I can't replicate the successful burn.

The 3 options unchecked in the write settings were: Prefer format with full certification Prefer format without spare areas Prefer properly formatted discs

Success. When I turn off these 3 write options (in the image attached), the BD-RE DL burns and verifies successfully on both layers. This was done right after a failed burn without erasing the disc. Not sure if all 3 need to be unchecked, but it worked. and here's the log: I 05:48:49 Operation Started! I 05:48:49 Building Image Tree... I 05:48:49 Checking Directory Depth...

I just tried perform OPC ...still no luck. I'll try a new disc and full erase it a few times and see what happens. I can confirm though...using the same disc...if I burn the 50GB dual layer disc with only 25GBcovering one layer, it works fine.

Hi, I've been having problems burning to bluray Dual layer rewritable discs. My burner is an "LG HL-DT-ST BD-RE WH14NS40" The bluray disc is "Verbatim BD-RE DL for video 50GB 2x I just updated my firmware to the current version 1.03 to try and fix the problem but still have the error. It completes the burning but when verifying, the I/O error pops up at 51-52% complete. Looks like the error starts at the first sector of the second layer of the blu ray disk. I've had no issues with burning a single layer BD-R 25GB Any Ideas? thanks Here is the log: I 20:29:05 ImgBurn Version 2.5.8.0 started!
