I’m using windows 7 32 bit and I want to use the blu-ray discs for data backup. The 25GB single layer discs work fine, but when I insert a 50GB it just makes a clicking noise in the drive and never mounts. I have tried several verbatim BD-R DL (hardcoat, whatever that means), and also several mitsubishi kagaku discs and none of them work. Any ideas? It’s driving me nuts. The drive is new, as is the windows install.
Thanks in advance
