To Err(or) is human:
My apologies for grossly simplifying:
'Error 0x80020022' means basically the same as ''Cannot calibrate laser..'
It cannot calibrate because it can't communicate is more or less what I meant.
My point was that the burning process still evetually errors out and that the actual error definition does not point to the nature of the problem, and can be misleading. For example 'Cannot calibrate laser...' would naturally lead to the assumption that there is a problem with the laser or drive itself. But for most, the drive had functioned perfectly until the upgrade. Res ipsa loquitur, the OS upgrade process has bugs and the drive is functioning perfectly. It's the OS (or IMHO the EFI) which is the problem.
Changing Error Messages:
The change from one error message to another can be explained by the DVD drive being region specific. The region check or error message/de-bugging could have a glitch where different error messages are returned dependent on language preference. For example: if the system language was set to Japanese, the error message 'Cannot calibrate...' may not be understood by the user, thus a code is returned instead. English messages for english speaking users. I believe the nature of this bug rather points to the real problem, and not the error message itself.
Static in the Air:
Even mild static is enough for dust to stick. The laptops I have worked on/repaired all had extremely dusty insides, with the fans and surrounding the fan casing being especially bad. Yes, the speed of the fan blade is directly proportional to the static that can be generated (faster = more), however, the amount of static needed isn't the sort where there is electrical arcing. I'm not talking about lightning bolts firing out of the back of your laptop (although that would be quite cool to see).
Everyone needs a Genius, not:
Don't know which 'Genius' you spoke to, but they all seem to give different answers from one to another. CD lens cleaners are usually a normal DVD disc with one or several little brushes attached. Normally they are not recommended becasue the cheap ones with poor brush quality can damage the lens. I bought an expensive one (Philips). I have never had one jam or damage my drive, but it is true that the brushes can interfere with the disc ejection rollers causing them to not grip.
Enough (hot) Air:
This is exactly the kind of blog conversation digression that I can't stand. I don't want to argue. If you want to blast air into your laptop, go for it. I won't be. If you have a nice clean laptop, that's really great. I wish mine was, but I freelance and work in at least 3 different studios and on the road (sometimes working outside too).
The Real Problem:
The point is that Apple is not addressing this problem. This we all can definitely agree with!
I have not been able to use my MacBook Pro to burn discs for over a year since upgrading from Tiger to Snow Leopard (including booting to other OS's, using external burners, and different media brands). Other people have had exactly the same problem before these OS versions and now after as well. It seems crazy to me that Apple's solution is to either replace the drive, or in some cases replace the logic board. I would really like to know the truth behind the problem. If it is as simple as a firmware patch, then they would've released a fix by now. My gut feeling is that it is a much more complex problem, rooted in the subtle differences in hardware revisions from model to model. If this is the case then there would need to be different EFI and SuperDrive firmware versions for all the combinations of hardware. More importantly, it would open the door to recalls and repairs on a massive scale. Does anyone remember the famous scene in 'Fight Club' about car recalls and why they don't do them?
The next Mac:
I will need to upgrade by spring of next year. I intend to have completely phased discs out of my life by then (I will deliver content to clients via the Cloud). I will purchase the 3 year extended AppleCare and back-up via Time Machine daily. When something (and I mean when and not if) goes wrong with the new laptop, I will send it away to be fixed and demand a temporary replacement which I will restore my back-up to. I have wasted far too much time sorting out and fixing my machine, rather than working chargeable hours for clients!
