That's the little flat ribbon cable that connects the hard drive to the logic board. So unlike the Genius bar, I can quickly diagnose a bad hard drive without having to infer the problem through symptoms.īut one problem that I've noticed really being on the rise lately, is a failing hard drive cable in MacBook Pros. While Apple's own tools (hardware test, Disk Utility) do almost nothing to positively confirm a failing hard drive, there are several other tools (SoftRaid, SMART Utility) that can read the SMART data and tell you for sure that a drive is failing. By far the most common thing I do is replace failing hard drives. I've been fixing Macs professionally (not through Apple) for well over a decade now.
