Yeah ...and if the comp is in a environment where much dust, fine cat hairs, etc. exists, the particulates are sucked into the case of the comp, and the lens on the laser can collect crap. Sometimes you can brush off the lens without removing the case on the optical drive to clean it. (there are special disks with brushes on them for this purpose) If someone smokes a lot and the comp is in a location nearby, the lens will be soiled with crap that only alcohol or such can remove. In this case you have to remove the case cover on the optical drive to be able to clean the lens though. Sometimes the rails (rods) and screw drive which have lubrication on them collect dust and absorb the lubricant and thus the optical mechanism binds occasionally, cleaning the rails and the screw, then adding a SMALL amount of lubricant can sometimes bring it back to life. But it would be a chore most would not attempt as optical drives are rather cheap these days. More than likely as someone else mention in this thread there is or was some crap on that disc. Sometimes washing the problematic disc with dish soap and water, and drying with lintless cloth works. If there are minute scratches on the disk, I have polished them out by using a very, very fine pumice liquid polish to remove them, (glass polish for example) then made use of "dd" to pull the data off the disc, making a ISO file for reburing to new media. dd if=/dev/sr0 of=/path/to/myCD.iso bs=2048 conv=noerror,sync or dd if=/dev/sr1 of=/path/to/myCD.iso bs=2048 conv=noerror,sync To find optical drive device(s): dmesg | grep sr[0,1,2,3] or hdparm -Ig /dev/sr[0,1,2,3]
