I have had my Lite on LTR CD R/W drive for about a year. Last year at about this time (when the drive was a little over a year old), the problem started. I bought a new drive (excellent rebate program) and that solved it. It started by not recognizing certain CD's. Now it won't recognize most CD's. I have tried my lens cleaner, but the drive won't recognize the fact that there is a CD in the drive. Is this a problem with these drives, or is there something else I should be looking for?
