The combo drive in my iBook (almost a year old) has started misbehaving when I try to import CD's into iTunes. It'll import the first 4 or 5 songs just fine, but starts making a louder and louder whirring. Then it kicks into this cycle where it just spins up and then stops spinning over and over without importing anything. Eventually iTunes will crash, occasionally bringing my whole system down with it. This started a few weeks ago on every few discs, but now it happens every single time. Burning goes off without a hitch, as does watching DVD's and playing CD's. I'm going to call Apple tomorrow, but in the meantime does anyone have any ideas as to what the problem might be? (I've already tried all the standard software troubleshooters - repair permissions, etc). Thanks!
