I've been struggling with my Yamaha CRW4416S lately. I went through quite a bit HW/SW debugging with it a few months ago only to find that the problem was a build-up of dust on the lens. I figured out that problem by using a lens cleaner as a last resort. I used an Allsop CD lens cleaner which is a CD with embedded nylon brushes. I hadn't had any problems with it since until I tried to burn some CD-Rs last week. The CD-R seemed to burn O.K. (using Adaptec Easy CD Creator) until the very end when it stated that the device reported errors (no specifics). Tried a couple CD-Rs and a CD-RW with the same result. Tried reading some previously recorded CD-RWs and the reader didn't detect the disk on all but one of the packet written disks. It can read an audio CD-RW, previously recorded CD-Rs, and normal CDs. I used a pressurized air blaster this time (forgot about the lens cleaner) but when it failed I went back to using the lens cleaner. No difference. I've determined that the problem is the drive itself as it can't detect the presence of these disks (amber light, versus green) even w/o the PC being powered on or being connected to the SCSI bus. I flashed the drive but it didn't help. I think I may have fouled the lens with the air blaster but its odd about it not detecting just packet CD-RWs (except for one). Question is ... 1) does the lens fouling sound like a likely explanation and 2) is this something I can easily get at for a more direct cleaning? Anyone have an idea what shops charge for such a cleaning?
