I have an LG WH08LS20 drive and am using memorex BD-RE. I've never had a problem using this disc before, but everytime I want to erase it Imgburn tells me I have to format it first. So, now I wanted to burn something on the disc, so I pop it in and it tells me I have to format it first. I clicked OK and then it says 'Erasing Disc...'. And now it just hangs there. It doesn't give me a percentage or anything. Just 'Erasing Disc...'. The blu light on the drive is flashing, but as far as I can tell nothing is happening.
