They just hang for a while randomly, then come back. Computers with bad cables don't crash, or freeze.

#MAC UTILITY TO DETERMINE WHY IT IS SLOW MAC#

But that's not how things go in the out-of-warranty world of independent Mac repair. I know the official way to diagnose a problem is to start replacing parts until the computer is fixed, and that last part was your problem. I know all about Apple service procedure. because, there's no way to directly confirm the cable is the problem. I never really know if it's going to fix the problem or not though. But I've replaced a lot of these drive cables and I'm doing another one tomorrow. You might think 'come on, how often does a simple cable really go bad?' Well, I've never had a traditional desktop style SATA cable go bad. This is a much harder problem to diagnose, because it generally acts just like a system with a failing hard drive, but the drive will pass a real SMART test with flying colors. 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.Р”В«ut 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.
