Take the tray apart and underneath the laser etc there are 2 small hex/allen screws which the laser's rails are resting on. one or both have probably loosened up during use so just need tightening. when i did it one was pretty solid and other was loose ish. give them a lil quarter turn then test it while its still open. just make sure you dont tighten it too much and you can just make tiny adjustments till the lasers back in the right place. and dont turn the xbox on without the drive connected cuz i hear that gets you banned from xbox live. sorry if this is confusing cuz im not that great at explaining things lol. hope it helped:D
