I think i might have damaged the yellow ribbon that needs to be reinserted into the new sata cable because i recently installed one and had it fail 2 weeks later and just got a new one that isn't loading up the sign-in menu but at least begins to read the hard drive instead of going straight to the ' ? ' folder. However, it will just continue to read the hard drive and stay at the loading screen with the apple icon and a spinning gray loading wheel below it without any progress. Any thoughts? I was thinking the yellow cable could have somehow been damaged. Does anyone know the name of the part with the yellow ribbon? It is connected to the bracket that sits below the hard drive.
