Hard Drive Cable Repair for a 2010 Macbook Pro
One day after my Macbook Pro did an update, it began to run more and more slowly. It eventually froze and wouldn't even boot up. At startup, it led me to a blinking folder with a question mark in it. After doing some research, I read that sometimes when the computer does an OS update some files go missing or cannot be found.
So I got out my startup disk and booted the computer off of it. When I went to do a diagnostic on my hard drive, the computer couldn't even find it! Knowing that my wife, even being the prankster she is, would not take out my hard drive, I started to worry that either my hard drive was damaged and didn't work, or the computer didn't read it.
I took the hard drive out and plugged it into my wife's computer via a usb connection. It appeared that everything was in working order so that led me to believe that somehow the cable connecting the hard drive to the motherboard stopped working. Once again, after some quick googling and reading some forums, apparently this hard drive cable stops working in a lot of computers. That led me to make the decision to replace that specific part.
The repair was relatively straight forward. The guts of the macbook pro are set up in such a way that made it pretty easy to get out the hard drive and take out the cable. All you really need is patience and a really tiny phillips head screw driver...and if you're worried, some good instructions. I took off the bottom panel of the mac, unscrewed the brackets that hold the hard drive in place, and took out the part. To replace it, I did that in reverse order.
I have a few pieces of advice:
1. I mentioned that this was not a difficult procedure. It was easy for me because I read a few different tutorials (ifixit has a good tutorial) and watched a couple youtube videos before I did this, so I wasn't surprised by anything.
2. Make sure you have the correct tools, and be patient. It's a simple procedure, but those darn cables are fragile, and you don't want to mess it up before you turn your computer back on!
3. Store all of those tiny screws in something while you're taking your computer apart - they'd be hard to find if they fell and landed somewhere. I stored mine in a tiny tupperware container with a lid that snapped shut so they wouldn't go anywhere.
4. You may notice that the insides of your computer are really dusty - while you're in there, clean it out using some compressed air.
