Crossflash Lite-On LH-20A1PU External Drive

Hey Guys,

I was wondering what drives I could crossflash my Lite-On LH-20A1PU External Drive with. The main thing I want to do is regain the ability to Burn DVD+/- RW DL Discs since my drive stopped burning them again:sad:. What drives can I crossflash this one with?

Thanks,
Adrian
