My liteon was 24 speed cd writer was bought when they first came out at that speed and was good, but it will now only write at 8 speed. Fails at anything over that.I would not buy another liteon my old 4 speed teac was a much better drive never failed to burn a disc. also can read disc better than the liteon .I know a few people that have the same problem. Since i punched the tray in in a temper the cogs for the mechanism must have stripped some teeth. :-o :-?
