The last time I tried to insert a disk it would not go in, something (not a disk) was stopping it once it had traveled about half way in. I then noticed that when waking from sleep or turning on, the normal noise was very different, cut short, and sounded like it was struggling against something. I believe the mechanism of the drive has somehow failed. Does anyone have any solutions? It is a iBook G4 1.33GHz with 1.25GB ram installed if that helps. Any advice is appreciated!
