Nice to hear that it was the mechanical dust situation that affects these drives the most radther than an electronic glitch. Quick fix, but I still prefer to do it myself so it can be visually inspected rather than relying on a disc cleaning system to get the debris out. That may work on some lenses, but those with the small rim on the laser lens doesn't allow the cleaning media from a commercial cleaning disc to get to the outer edge of the lens and some debris remains. Manually cleaning the lens gets all of the debris.
In any event, glad that things are resolved.
