My Problem

I bought a used MacBook Pro 13 Mid-2012 and it would only recognize a 250GB hard drive or smaller. The seller said the original drive went bad and they replaced it with a 250GB drive. I bought a 500GB SSD and discovered the problem when the MBP failed to boot from the drive. It would not even recognize a 750GB drive. Both drives worked fine in a USB enclosure. The Apple Store hinted it was the hard drive cable, but they would not repair it due to the original drive being replaced with a third-party drive. I wanted them to test the logic board to see if the SATA chip was bad.

My Fix

The installation was simple. I had the new cable installed in about 20 minutes.

My Advice

If you think your hard drive went bad in a MacBook Pro, test it in an external enclosure first. The hard drive might not be the problem. It might be the hard drive cable.

My Problem

I attempted to replace what appeared to be a bad Hitachi 5400 rpm spinning disc in my mid-2012 macbook pro 13". I purchased a new 1TB Crucial SSD for the system. Sadly, when I installed the drive and attempted to restore from a Time Machine backup, the drive would throw "read" errors and disappear from the bus. The ultimate problem was not the original spinning disk, but the actual SATA cable. I ordered a cable from iFixIt and had it overnighted.

My Fix

The repair required no more than 5 minutes. I removed the old cable being careful not to bend any pins on the main board. I installed the new cable being careful not to kink it and jeopardize the integrity of the links. On the first boot, magic! Everything is sound. The SSD is blazing fast compared to the spinning disk.

My Advice

Use a good set of jewelers screwdrivers to remove the hard drive brackets and the sata cable screws.

My Problem

So, I had a friend over, and we were doing some drinking, and I had my Macbook (Mid 2012 Unibody) plugged up to the tv. Apparently after I went to sleep my friend started feeling sick. He ended up vomiting and I suppose he couldn't make it to the bathroom, because he ended up throwing up in the empty pizza box beside my Macbook... well... mostly... I woke up the next morning to a puddle of puke about the side of a pancake on my open computer, right on the keyboard, and by the looks of it, it'd been there for a few hours. I immediately shut it off and pulled the battery, but the damage was done. I cleaned it off and let it dry for a few days before turning it back on (amazingly, it still ran). Several keys were inactive or triggering other commands, my trackpad was being janky, my hard drive was making weird noises, my battery life had decreased by about half, and my optical drive was completely broken. I'm a working DJ, and learning music production and sound design, so obviously this was a very big issue for me.

My Fix

I ordered all the parts (at least I thought I did) and got them in the mail a few days later. I downloaded iFixit's mobile app for iphone (SUPER HANDY!) and got to work. I had to disassemble the entire machine in order to replace the upper case, and then as I was putting it back together I was able to just swap out old parts with replacements. I opted to get a hard drive caddy and swap out my optical drive with a second hard drive (now rocking 2tb of storage, it makes me very happy) since I have the external superdrive for the Macbook Air. With iFixit's guides on the app, it was a breeze from start to finish and I got it all done in a matter of hours. I consider myself a handy person, but I know nothing about computer repair, so for me to be able to flawlessly repair it to fully functioning status was a pretty great feeling. Couldn't have done it without the step by step guide with greatly detailed pictures. I discovered a couple days later that my airport/bluetooth card was also damaged by the incident, which is not a huge deal, just an inconvenience and I plan on replacing it when I get my next paycheck.

My Advice

If you're replacing your upper case on the Unibody model A1278 (not sure about other models) the guide doesn't mention it, but you need to pull the battery level indicator off of your old upper case and transfer it to the new one. Another thing I didn't know that fortunately didn't bite me in the hind quarters, was the risk of static shock. I didn't know this was a thing, but a simple static shock discharged from your body to your computer's sensitive inner parts can practically destroy your computer, so before going into your computer's innards, make sure to look up online how to ground yourself so that you don't risk killing your beloved computer. Lastly, if you decide that you also want to replace your optical drive with a second hard drive and intend to use apple's external superdrive, be aware that the drive was only intended for use with Apple computers that do not originally have an optical drive, so it's not a "plug and play" accessory. You have to go online and find directions for rewriting one of the scripts so that it will allow the drive to be used, just be careful because an incorrect sudo script can seriously mess up your computer.

OH! And for the love of all things holy and unholy alike, MAKE SURE YOU KEEP ALL THE SCREWS SEPARATE AND WITH THEIR RESPECTIVE COMPONENT! I cannot stress this enough. You will save yourself a major headache. I used sandwich bags and labeled them with a sharpie.

My Problem

The main issue was that my hard drive was no longer being recognized, even after purchasing a brand new hard drive.

Here is (a long story) how I got there:

My 2012 Unibody Macbook Pro 13" started to lose its perform capabilities one day in January 2015. I was running Mavericks for a year so on 4GB RAM and haven't been experiencing slowdowns or heating until then. Not wanting to spend money on repair and short-on time with school, I did the recommended Repair Disk Utilities, PRAM resets, SMC resets, and overall cleaned my mac from unnecessary things. My biggest mistake was upgrading to Yosemite (40 hours) and the macbook became unusable. I upgraded my RAM to 8gb for $171 from a campus tech service (too expensive). It was still too slow so I put in rEFind boot manager so I could dual boot LinuxMint (its amazing). But suddenly the flashing question mark appeared instead of the boot loader.

My Fix

The repair was simple. The instructions was clear and pictures accurate. I was concerned about static electricity zapping the internal components so I wore an anti-static strap.

After installing I turned the macbook on while pressing option key and my hard drive was found, with all the partitions I created as well. rEFind will not work so I can no longer boot into LinuxMint but the performance of Yosemite greatly improved after replacing the cable.

My Advice

Don't overheat your computer. Don't upgrade to Yosemite unless it its a clean install. Although I may have some batter issue, for the time being, the cable is the BEST solution to a non responding hard drive. I wasted $165 (with shipping to Canada) on a brand new hard drive that didn't solve anything. If I went back to the campus tech guy I would've paid off two university courses. Fit it yourself!

My Problem

My laptop could not locate my hard drive software start up. It displayed the grey screen with the folder that had a question mark on it. My school tech bar tested both my HD and the cable for me. The HD worked perfectly and the cable worked with 1/4 of the test HDs, so they suggested I could take the risk and just buy a new HD cable.

My Fix

I borrowed a friend's old laptop for a few days. I received my new HD cable from iFixit in 3 business days. My school tech bar installed it for me for free, which only took about 10-20mins. The start up is a bit slower than it used to be :( but it runs fine.

My Advice

If you laptop can't find the startup software, don't panic. Your HD is probably still functioning, just buy a $50 new cable and you'll be fixed in no time. If you want, you can even buy the small screw driver and change the cable yourself!

In the meantime, if you need anything off your HD, bring it to a tech bar and ask them if they can hook up your HD like a USB on another computer so you can transfer some files to another USB.

*sorry don't have photos.... my cable is in my laptop now and I don't have a screwdriver to open it up again for y'all to see :P

My Problem

Pinwheel showed up every minute, started for 30 seconds and made it impossible to get anything done. Seems to be a common problem in 13" mid 2012 MacBook Pros. I tried nearly everything else including reformatting and running back my os to mavericks but nothing worked until I replaced the hd cable.

My Fix

Super easy

My Advice

If you have a mid 2012 MacBook with a pinwheel problem try this first.

My Problem

The Macbook Pro was working really slow. My first thought was a failing harddrive, so i took it out, at did a test, no error. Then i thought it might be that ribbon cable. Since i live far away, i wanted to order from ifkxit because of my previous success with them. It took only 6 days to receive the package ( which is pretty impressive by the way), and everything was of course in order :)

My Fix

I replaced the part, and everything is working properly. The customer has paid, and we both are happy with the fix

My Advice

If these Macbook Pro's are working really slowly, pay close attention to that ribbon cable. I have expeienced it quite often that the issue is with the cable and not the harddrive it self.

My Problem

My hard drive was not being recognized and I thought my hard drive had gone bad. So I had replaced it with an external drive for a while till I figured out the problem. The hard drive cable had gone bad and I was being led wrong by the "professionals" I had consulted and spent to much money getting a new hard drive when I didn't need it.

My Fix

The replacement did not take long and was very painless. The hardest part was sticking the wire down below the hard drive and keeping it there. However, the lesson here is check your hard drive before buying a replacement so you know if it is the hard drive or not. This apparently was a common problem with 2012 macbook pros hard drive cables going bad, but no one wanted to tell me.

My Advice

Please make sure that when people are checking for a new hard drive it just isn't their hard drive cable. Sure, I love my new hard drive and it is an upgrade, but I wish I had spent less money on my repair.

My Problem

I brought my laptop to the "....squad" for repair. After 2 weeks of excuses, they finally determined the problem was a hard drive cable.

My Fix

Simple fix right? Order the part, then install. They ordered the wrong part! This is where IFIXIT comes in. I decided to find the part myself, found your website, bingo. Your site is clear, precise, and easy to navigate. Since "dumbassquad" had my laptop, I brought the part to them, and they installed it.

My Advice

Go to IFIXIT first.

My Problem

My mid-2012 Macbook Pro had started to become sluggish. The rainbow beach ball had been rearing it's ugly head more and more. After doing some research on the forums, it became obvious that the hard drive cable connected to my SSD was to blame.

My Fix

Using the guide provided by iFixit, the repair was a breeze. The pictures provided were clear and their procedures were accurate. From unpacking the cable to turning on my computer for a test run took about 15 minutes.

My Advice

Keep track of the screws and where they go. I placed them on a white piece of paper and labeled where they went. While your computer is cracked open, use this opportunity to clean out the inside using a can of compressed air.
