We have one that sounds similar to yours......a couple of things to check: I know you mentioned that you were 99% sure that the disc was finalized...on ours, after we hit the little finalize button it says "finalize?" and then we hit another button to confirm (this button is actually a bigger knob that on ours is the track selector - but you have to push it in instead of turning it side to side)....then it asks "are you sure?" and you have to hit the big knob button again..Anyway, after you confirm the second time it will take a while to process and you will be able to see this happening...ours says ("TOC reading..) or something like that and it has a clock counting down until it's done. You have to wait until it's completely done before you take the CD out. We have lost a LOT of recordings in the early days before our tech team got used to all of the steps. They make it to where if you miss one of these steps you will lose the entire recording...ugghhh!! Anyway, I hope this helps! This is the most common problem that I have seen with these things - if this doesn't work though I have one more idea as to what could be wrong. Let me know if you have any questions and I'll help any way I can! :) - Crystal
I have a Macbook that has frequently had issues recognising CDs and sometimes DVDs. In my case the only way to recover the disc was to actually shut down, then restart and jam the disc with a credit card. This is the 'nuclear' option, but none of the 'soft' methods worked.
The machine has been better over the last year or so (running 10.5) but that was after a number of software updates from apple to address superdrive issues. I wonder if this is more likely a Snow Leper issue than an incompatible disc. I'd recommend checking on the apple forums for advice.
Hope you can find a solution.
