MacBook Pro 13 "(mid-2012) do not recognize all internal HDD or SSD

Hello, I have this very annoying problem with my Macbook Pro 13 "mid-2012.

Two days ago he suddenly shows the ""folder with a question mark gray ' screen. " Reading online, I saw that many have had this problem in the past and that usually to fix just do this:

-Restart the Mac, press Cmd + R, then the utility disk, check and repair the drive.

I tried, but there was any Macintosh HD. There is rather a "disk0' with a score of"Mac OS X Base System.

I tried also this, without success:

-Remove the HARD drive and using an "all in 1 HDD Docking Station" try opening the hard drive of another Mac. It says that can not open the disk but I can erase it (did not, I still hope to recover data in the future with some software).

-I already upgrade my Macbook Pro with an SSD, thinking about my drive HARD has been compromised, I bought a Samsung SSD 750 EVO (250 GB) and I replaced the HARD drive.

-J' have formatted the SSD format "Mac OS X Extended (journaled)" and, from another Mac, created a boot USB with El Capitan installer disc.

Then, with the SSD instead of HARD drive, I did all these things:

-Start the Mac, press Option, start the USB key. But no "Macintosh SSD" has been shown when comes to decide where to install El Capitan.

At this point, I was very confused and tried the last chance:

-Start the mac without internal drive but with the SSD in the docking station. Boot from USB and try to install El Capitan on the SSD. And it worked!

But stil does not work when I put the SSD inside the Macbook. Is possible whether the Sata cable who, from one day to the other, stop working?

PS:

I tried also Reset of the MSC and the Apple Hardware Test extended, giving "No problem found".

I also tried to unplug the Sata cable connectors and clean the cable with a handkerchief, then incredibly SSD Macintosh appeared at the start of the USB, but installation failed at some point. And next time, I tried the SSD disappeared again.

This problem is driving me crazy and I hope someone can help with suggestions. Thank you

  • MacBook Pro (retina, mid-2012) will not start

    I have the mac above and I have a weird problem. The mac wouldn't start, I could hear the fan running and if I pressed the power button I can hear her stop.  There is no visible display or no light. the shift lock lights.  Charger lights work normally, if I reset the SMC, the light on the charger goes from green to orange and green. I contacted Apple and they could not help, we have also reset the PRAM.

    I left it on and then when the battery was completely dead, I plugged in the charger and tried to turn it on, I was rewarded with the icon of the dead battery, progress! After a few minutes that he started ok, I had the Apple logo and progress bar and then start.  Alls well well except when he went to sleep, she would not start again until I have go through the flattening of routine battery.  I now have reboot, stopped, started from cold, sleep and he waken up - everything looks ok.

    My question is there will be any newspaper to show what was causing the machine does not go to sleep?  I lost confidence and am very reluctant to go to the genius bar as I don't think they understand the problem.

    Thanks for reading

    All saved entries are found using Console in your Utilities folder. Is simply a software problem, then you can erase the drive and install a new copy of Mac OS X. If it's a hardware problem you need an appointment with Apple Genius Bar for the service. If you need a Apple Store - find a store - Apple.

  • Should I replace logic board or cable hard drive? MacBook Pro 13 mid 2012

    Hello guys I suffer for the last two weeks of my Macbook Pro would be grateful if you help me.

    Summary:

    A few months ago my mac has been slow and when I restart or stop it would take a minute or two, what has not happened in 2012-2014. In 2015, I decided to upgrade my SSHD HDD - Seagate 1 TB (that I'd need more space and a better performance). After that the upgrade of SSHD everything went well, my mac has been rapid, the battery has now 8 hours of battery life (440 + cycles). Overall it was a great experience! However during the night my frozen Mac even the mouse cursor, so I closed my Mac and it set in motion this time he showed me an icon of the slash. I disassembled my Mac and handed the stock HARD drive. This time, he showed the white screen without the disks. I tried several boards of various sites and one from the tip which has been WORKED safe mode! When I restarted, he returned to square one... I used the same trick but it didn't work. Now I see that a white screen on both discs, sometimes the issue icon flashes. Just for you find the hard disk turns but does not recognize... Although she acknowledged on my other Mac.

    I just remembered something just before this incident happened, I was cleaning up my Macbook with a small wet towel size (including the liquid soup inside) and then I cleaned the screen, the trackpad and keyboard (some liquid went inside the thing black screen and some of them inside the edges of the trackpad) but I them rinsed quickly. After 2 days, the slash screen appeared, and that's how it started.

    I removed the battery to see if there is any corrosion or something unusual about this, I also checked the trackpad, and it wasn't any dry liquid or dust, etc.

    Get to the point:

    Currently, I use my Mac through an external SSHD and everything works fine, but I want to stop using this method and thus solve the problem.

    Issues related to the:

    What exactly is the problem? Is my logic damaged Board and keep my HARD drive to recognize?

    Do you think that my card is fine, but I just need to replace the cable from the hard drive (821-1480) to a new?

    What happens if the hard disk thing stuck on the logic board or is damaged?

    Please help me and I'm sure that others are also facing a similar question. Another note, why some users claiming that their disk cable hard is to failure after replacing several times?


    We do not know "What exactly is the problem?". Get out your computer to an authorized for assessment service center. I suspect that you have caused water damage when the water and soup entered into your computer. Be prepared for a fix expensive since the water, not the soup ir and electronic works well together.

  • Go to bed before exhausted battery MacBook Pro retina (mid-2012)

    I hope that someone in the community can help with this question.

    I have a MacBook Pro (mid-2012) with a battery 3.2 old Yes and less than 300 cycles. I think the battery is depleting faster (which is natural after 3.2 years) but benchmarking between percentage left and the unit goes into mode 'sleep' is meaningless. For example, tonight the battery came into sleep mode with 16% left on the screen - sound almost if the MacBook thought it was exhausted.  I have heard do NOT need calibration for that MacBook Pro, but it feels like it does.  Which leaves me feeling very concerned on what continues.

    Things I've tried so far:

    1. full reset SMC and General reboots.

    2. a full discharge and recharge (attempted calibration despite says that's not necessary).

    3 using the activity monitor to see if something is sucking energy unduly.  (Which there isn't, and everything seems normal).

    4 using the battery health app to look at the State of the battery - said its 87% in good health and no calls for service or replacement.  ('Normal' status).

    Anything related or apparently wrong - but certainly go faster down and switch mode 'sleep' around 16 to 19%.

    All the words of wisdom of the community?

    Thanks in advance.

    Brad.

    A full release just the risk damage to your battery. Are you sure that the Mac is not just go to sleep as it was designed to do? Try to reset your default energy-saving preferences. If that does not resolve the problem, maybe it's a problem with the operating system, in which case you should try to reinstall OS X by pressing down the command key and the R key as soon as you see the Apple logo at the start of your computer to the top and then clicking "reinstall Mac OS X" and following the on-screen instructions.

    I hope you find this information useful.

    Best regards

  • El Capitan on a Macbook Pro for mid-2012?

    In other words - my OS upgrade needs badly. Slowdowns of Safari and page gel side, I start to have problems of compatibility.

    I stuck with the Lion of the mountains (OS X 10.8.5) for a while now, and as much as I love him, I decided that I have to upgrade.

    In other words, how can I expect to run on a Mid-2012 medium-to-high range Macbook pro (chart below)?

    My main concerns are running speed and battery overall utilization;

    I do a few games, nothing too big (Guild Wars 2 and Civ 5 are the heaviest), and my use of safari is quite heavy, so speed it would be a good thing. I have the laptop plugged in most of the time, but I would like to know just would get worse how the battery life.

    First of all, Merry Christmas to you all and hope that you guys are doing well.

    As the title says I am using the updated Macbook Pro Mid2012 Standard (Non-retine). In any case the introduction of the metal, shouldn't this smoothly? I see really no improvement in terms of game performance other than an increase in the value of 1024 MB to 1536 MB vRam. More it overheats a lot even in normal operating conditions (such as surfing the Web or watching streams etc..) Just to let you know that my Macbook Pro has a minimal dust inside the unibody shell.

    Would be grateful if you help out me

    You have several distinct concerns:

    For metal application support, hardware and software, please read this this Apple Support document: list of computers Macs that supported Metal - Apple Support

    and this message:

    Re: el capitan and metal, test application?

    Energy concerns please read that apps can affect Mac performance, battery LIFE, temperature and fan - Apple Support activity. Identify the process or processes causing excessive consumption of energy and to evaluate the performance of your Mac when these processes are used or not used.

    Just to let you know that my Macbook Pro has a minimal dust inside the unibody shell.

    Most dust internal preventing the proper heat dissipation accumulate in the fins near MBP fan extraction or amateurs (model 13 "has only one). Exhaust fans speed will increase as necessary to achieve their reduced capacity to dissipate heat. If that does not work, the next thing that happens is that your Mac will automatically reduce its processor demand so that it produces less heat which must be dissipated. If this still fails to keep temperatures limits, the Mac will just stopped on its own. Excessive dust should be removed, but it is better to have Apple or a FSAA do, due to the high probability of damage should you decide to do this yourself.

    Please be advised that fan of higher speeds tend to exacerbate the dust because moving to a greater volume of air per unit of time only tends to draw in additional dust. It's one of the reasons for the third system hacks that bypass the cooling system of the Mac should never be used.

  • MacBook Pro (retina, mid-2012) Apple Hardware Test 4MEM/9 error code / 40000000:0x794a4390

    The first AHT I ran gave me the code of error 4MEM/9 / 40000000:0x79456d90.  I shut down the computer as suggested and then re run AHT and received the error code 4MEM/9 / 40000000:0x794a4390.  The two tests have been extended to tests.  Is that going to be an expensive repair?

    The error indicates that there is a RAM problem.  Since you have a MBP of the retina, the only alternative you have is to take the MBP for an Apple store genius bar.  (RAM is welded in a MBP of the retina and is not accessible to the user)  The assessment will be FREE and they will advise you of all the costs involved.
