I am having a problem with the disc not being read on my Lite-On 163. When I first put it in the drive it spins for a while and eventually stops. Then when I try to run a player I get a disc not loaded error. If I eject the disc thru the player, and then load it, eventually it loads. Sometimes on the first try but usually on the second or third. I updated the bios of the drive. I have cleaned the drive. It happens most of the time on about any disc. Anything I should try before replacing the drive? Thanks.
