I just got my macbook on friday and the only thing that seems odd is the cd drive: When i turn the macbook on the drive makes a noise. When i wake it up from sleep mode it also makes the noise. Playing cd's and dvd's is fine. However when i put a cd in the drive its really rough and loud as if the drive was crushing the cd or something. i dunno if this is normal and im just being anal but can someone comment on this?
