Hi all. I have 2 DVD+R/RW-DL drives, both of them LG. Master=GSA-H20L (LightScribe) Slave =GSA-4167B Now for some reason, I have no idea why, occasionally when I put a disc into either one of the drives, (but this happens more so with the Master one), they'll just fail to recognize a disc is in the drive AT ALL. It looks like they attempt to read it for a few seconds but then they just stop and the LED goes off. I open up My Computer and try open either drive and it says there is no disc inserted. Doesn't matter what kind of disc it, DVD, CD, Game disc, DVD Movie, Audio CD, it's happened with all of them. Sometimes a disc fails to read in one and I try the other and it works fine, or strangely if I run AnyDVD, that seems to make the drives recognize the discs suddenly. Anyone know what's going on?
