MacBook Pro 15" Core Duo Model A1150 Hard Drive Replacement
My new Hitachi drive has the "do not cover" hole right under the place where the IR and sleep sensors need to be attached. The stock drive had the hole on the other end of the hard drive. I just made sure the adhesive didn't seal off the hole, and I think it should be alright. Otherwise, install was easy and these directions were outstanding. Thanks.
