My laptop has a Toshiba DVD+RW drive fitted (fixed not modular). I don't have to much experience with notebooks, but this drive, although working correctly, seems to make very peculiar noises when it is operating. for example, after placing in a cd, it clicks (which is normal), then the motor makes this kind of rumbling noise, and it clicks a few more times and finally recognises the cd/dvd. when burning a cd, it makes this constant gurgling noise. in all, it does not sound as normal as a standard desktop's CD/DVD drive would sound like. is this normal, or is this drive about to die?
