Hello there I am presently experiencing problems with my superdrive making strange noises, spitting discs out and not even accepting discs unless i push right into the slot. Apple have advised that the drive is knackered and I need a new one. When i asked the cost they said £175. The mac is out of warranty and is an old mashshita driver UJ85. Does anyone know of a suitbale replacement? Apple have advised me that I can only purchase from them or an Apple Reseller. All help would be greatly appreciated.
