possible to replace cd drive in macbook?

sure its, possible. You might not want to, but it can be done.

 

if its under warranty, changing it will void that.
its not the easiest thing in the world, but sure, if you have the right tools, patience, and the right replacement drive it can be done.

 

I think you'd be better off just opting for an external burner. It'd be a lot less hassle, won't void your warranty, will be a MUCH faster drive, and will probably be cheaper. Just a thought.

 

Actually...

I just called SOHO computers here in Victoria BC asking the exact same question about my macbook 1.83ghz. They said that there is a DVD burner from mac that they can install, and quoted me a price and everything. It was pretty pricey, but they said that could do it. I ended up getting a LaCie d2 DVD+RW double layer external drive with lightscribe for about half the price. But it can be done, ask your local mac store.

 

Its actually pretty easy to replace the drive. If you are careful, and remember every screw, its not bad. Be careful though, its easy to break a ribbon cable and then cause yourself more trouble than its worth. I'd google "how to replace macbook combo drive" and there are a few good sites out there with tutorials.
