I just replaced my combo drive in my Ti DVI because it was chewing up discs. The cw8123 was replaced with a cw8122 that was pulled. The cw8122 is recognized by the PB but cds and dvds are spit out. There is no spinning wheel, no annoying alert, just some nice quiet whirrs, clicks and out comes the disc. Itunes/Dvd doesn't start up.

The seller is pretty reputable and knowledgeable and has a good rep here. He says it should work.....

Do I need a new driver and where do I find it.

Any ideas?

disks not recognized

okay, if you're certain the drive is Mac compatible, then you need something like
PatchBurn to get iTunes/iDVD to recognize the disks. (at least, I think that's what it was called). maybe xlr8yourmac has more info than I do

well, at least it's something. I guess you did the whole CUDA button reset, too..

Thanks, John, on your suggestion, I tried patchburn. It said the drive was supported and so patchburn wasn't needed. Xlr8yourmac said it was a compatible drive and it does show up on system profiler as apple supported.
If the CUDA button is the reset under the keyboard, I did that.

disk spitout?

okay, archangel, that shows you how much I know.
the CUDA is the little button on the motherboard that you're supposed to press
a few times when you install hardware. other than that, does it show up under system profiler, and is it set to "master" rather than slave

these are all just suggestions.I'm just guessing here
'cuz I"m out of my league here.....maybe O'grady's power pages or someone else can help more...even xlr8yourmac???

You usually never have to reset the CUDA button when you install new hardware. (if ever -- you should never have to.) As well, if you do reset it, hit it once for less than a second - holding it down for longer periods of time or resetting it multiple times will crash the PMU chip, and on rare occasions, destroy the logic board along with it.

So, yes, it is recognized under profiler. How do I know the master/slave thing?

Thanks, for the CUDA, info was a bit late but no harm done. I held it down for a five count, which is my usual for reset buttons. Why, I don't know.

What I'd like is the equivalent of "no disc" display, so I'd know it was simply the optics were screwed up. I have no info with what is happening.

Yes, this is a bump but only because this may turn out to be the first time you guys have failed me.

99.9% of the time a drive spits disks out, it's defective. It's happened to 2 of my Superdrives. I don't think there's any amount of resetting/fiddling with the drive that will make it work again. I think you just got a brand new lemon.

Always take Vexel's advice over mine, and the following is definitely an obscure stab in the dark, but here's what I've come up with:

When I'm burning from iTunes in my iBook, if I slide the blank disk in before starting the burn, I get an error message saying "Please insert disc" and the blank disc is then spit out. I then push the same blank disc back in, and it burns.

I am hopeful for you, but would be shocked and amazed if your problem was that simple. Good luck!

Yes, I'm afraid it may be a lemon.
Is there any way that something might not be hooked up right?
It is recognized, so it is connected.
It does pull in the disc, whirr it around so it's getting power.
It says driver apple supported so it shouldn't need a driver?

Nothing shows up on the desktop.

Perhaps run a diagnostics check on it? I think TechTool can do some tests on cd/dvd drives, I'm not sure if there are others.

Before I completely give up, can somebody tell me what the three cables on the drive do? One orange tab goes directly to the board; a smaller orange tab takes a right angle to the board; two wire, pink and white go into a clip at the other end.

Thanks.
