So as per jadburner's comments, SE-506SCB can't currently scan 100 or 128GB BDXL discs at least in OptiDriveControl 1.70. However, if it can do 50GB DL, it's still interesting. I've ordered one for myself.
BTW, I've tried contacting Erik Deppe (ODC author, via his ODC contact email), but haven't heard back from him. Anybody know if he can still be contacted somehow?
Thank you, I am humbled.
Very very interesting find. The screenshot indeed shows that it can be used to Scan 100GB BDXL in Plextools Lite, even if a bit messy:
I can't seem to be able to find Vinpower LG BH16NS48DQ drive for sale, even through the Japanese eBay sellers. Anybody find a source that is able to sell to EU?
I have already tried from amazon.co.jp, which has stock, but it states: "this item can't be shipped to your selected address" (within EU). Bummer.
Amazon.co.jp URL: http://j.mp/BH16NS48DQ
Another possibility, would be a full fw dump and cross-flash (if it is internally the same as LG LG BH16NS48). I have asked yss, if he could provide a full firmware dump of the BH16NS48DQ drive.
Yes indeed, offered by LG USA. However, not for sale on newegg/amazon.com/microcenter.com/ncix.com/overstock.com/adorama.com/bhphotovideo.com/rakuten.com. Sigh.
The search continues.
Thank you all for your expertise and valuable input.
