Hi Folks. I've run out of ideas and should have come here sooner! I want to burn 128GB BD data discs. I want to use an external USB-connected drive. 2 or 3 years ago I purchased the Buffalo BDXL drive BDR-209M. It worked fine with 25GB and 50GB discs. And then a year ago I got hold of 100GB discs and it did not recognise them. After a protracted discussion with Buffalo they agreed an exchange. The "new" BDR-209M does indeed read and burn 100GB discs, but does not recognise the Sony 128GB discs that I recently purchased. Buffalo claim they have tested it and it works, but they are still looking into it (I have no idea what they are looking at - I have given them nothing) and will get back to me. !! So I bought an ASUS BW-16D1H-U which also says on the tin that it can handle 128GB discs. Like the Pioneer (sorry, Buffalo), it does indeed read and burn 100GB discs but does not recognise 128GB discs. I had a discussion with ASUS support. They supplied a firmware updater tool (without telling me what firmware it contained) but it 'failed'. They said, because it's the same level as installed. That's perhaps not surprising as the unit is new. They have just told me to ask my supplier for a replacement or refund. I now have little confidence that a replacement will be any better. Am I doing anything obviously wrong? For example I have 3 BD burn tools: ImgBurn, BurnAware and Power2Go, latest versions of each. Should I be trying something else? I have blank 128GB discs, but it might be useful to have a 128GB disc containing data. If so, could some kind person (preferably in the UK/EU) burn a disc for me wth some random data if I supply one? Here's what BurnAware sees of my drives. Vendor: PIONEER Product: BD-RW BDR-209M Firmware version: 8.50 Serial number: RHDL026797WL Connection type: USB Interface: Serial ATAPI ...
