Thanks Alex. If you want to clean the internals there are 4 screws holding the top of the drive. There is one a bit longer than the other three. Make sure you mark the hole for the longer one. Removing these screws and the top of the drive exposes all of the areas to be cleaned. Also, if anyone tinkers around with these and other computer devices even occasionally, it will make your tasks much easier if you buy the Ifixit Pro Tech Tool Kit.
