i just tried to put a cd into my slot loading powerbook drive, but it doesnt go all the way in...usually the drive "grabs" the cd and takes it in...i tried a few different cds.....nothing..the cd wont go in.....i tried hitting eject...nothing....i restarted,,nothing...i went to my syustem profiler and under the tab for "disc burning" it says no burning device was found.....i REALLY need help with this badly...i leave for college tomorrow morning, and id need this fixed asap....any help is MUCH appreciated
