Last night I loaded a CDR into my PB to rip the songs into iTunes. The CDR got about 75% through, then my drive spun down to a stop and started making clicking noises. I had to force quit iTunes, then restart the PB to eject the cd. I tried another CDR (diffferent manufacturer) with the same result. I put in a game CD - played fine, ejected fine. I put in a DVD - played fine, ejected fine. I put in a store bought CD - imported all songs fine, ejected fine. tried a 3rd CDR - same results as the other two CDR disks. I'm at work now, ripping one of those "bad" CDR disks into iTunes on my Mac here. Seems to be going fine, so I am sure now that it is not the media, but the way my Combo is (not) reading it. Unlesss someone has an insight for me, I'll be making a Genius Bar appointment as soon as the Towson store opens this morning (PB is only 9 months old).
