I was watching a DVD from Blockbuster on my MacBook using the SuperDrive and the magnetic sticker that Blockbuster puts on top of all their DVDs came off and is stuck inside the SuperDrive...the drive still works, but you can hear the sticker 'clicking' when the drive is in operation and rotating. How realistic is it for me to open up the drive itself and remove the sticker without any major damages? I have found instructions on the web for disassembling the MacBook itself to get to the drive, but do any instructions exist for opening up the actual SuperDrive to have access to the components?? Any help or suggestions would be great.
