I have this same superdrive model number (HL-DT-ST DVDRW GSA-S10N:), but mine is a macbook, not macbook pro. the drive, itself, reads the disk -- but the foam padding at the opening of the drive is fraying. the last disk i inserted required some force to go in, then got stuck and couldn't eject. i eventually got it out by grabbing the slightest edge of the disk with tweezers. do i have to replace the drive or is there another fix re: the foam padding? grazie mille!
