Replacement 120gb HDD not recognized in MacBook Air A1237
I just bought the 120gb Samsung HDD from IFixIt for my 2008 A1237 Macbook Air because the original 80gb HD died. I followed the install instructions implicitly and no matter what I have tried I can't get the HDD to be recognized by disk utility. I have checked the cables and made sure everything is secure and I still get nothing. Any tips on what I am missing or could try?
