Not sure if this is the best location to ask, but I have to see anyhow... Just wondering if anyone has had any verifiable experience with misaligned lasers in optical drives, and I was curious how they fixed the issue if they got that far. I'm asking since I have 2 optical drives-both DVD+/-RW and both have apparently failed to the point where they will either barely read CD-R/Ws and not read DVDs at all (Liteon SOHW-1633S), or not DVD media and CD media is read slowly (Sony DRU-500A). The other option I considered it being is powering issues, but-as requested before-I was wondering if anyone had similar issues with misaligned lasers, what the symptoms were exactly, and how they possibly remedied the problem(s). I would rather not toss these drives in a dumpster since they were rather expensive and still work somewhat. I have updated the firmware to the latest and greatest as per Lite-on and Sony's website, but it hasn't affected the overall operation of the drives. Many thanks! -Garrett
