Brand New OWC SSD Not Detected, Old SSD Corrupted

Apple Repair said the factory installed SSD (Samsung) was unrepairable and would cost $1900 to replace. I purchased a new 256gb OWC Aura SSD for $220 from ifixit.com (I live in New Zealand so shipping is a little more).

I installed the new drive into the 2014 Macbook Pro Retina and it is not detected in the Recovery menu (after holding CMD + R on startup).

  • Is not visible in the menu in Disk Utility from Recovery Menu.
  • I made a bootable HD using an old USB2.0 drive and tried to find it using Disc Utility, is not visible
  • Checked the ‘Show All Devices’ in Disk Utility, volume or drive is not able to be detected, it only shows the recovery partition.

Is it possible there is a problem with the logic board on the 2014 Macbook Pro? That the logic board is not talking properly with the SSD?

Update (02/28/2021)

Here are some board and socket images

Dis you follow the OWC instructions?

Remember! Your system needed to be running High Sierra or newer BEFORE you can install the OWC SSD. As your systems firmware needs to be running the newer firmware which the OS installer will put on doing the OS upgrades from Hgh Sierra and newer.

Did you try contacting OWC support to see what they say?


What OWC instructions? I follow theiFixit instructrions. OWC does not send any instructions.

And I don't think you can install High Sierra on the SSD before you install - or you need some specially configured mac or adpater box? The internet recovery only provides Yosemite.

I didn't know you could contact OWC support - thank you, I wil try them.

Did you follow the IFIXIT guide MacBook Pro 13" Retina Display Mid 2014 SSD Replacement making sure you disconnected the battery first?

I would inspect the SSD sockets contacts and look for a cracked SSD connector case. I’m suspecting the socket is damaged.

Thank you for your response Dan. Sorry for the late reply. I managed to get the laptop working another way by using an SD card installed with macOS. Now I have 2 x 256GB memory card and not sure what to do with them! Looking at maybe creating an external drive with the two SSD’s lol. Really appreciate your time.


@kingi - So neither Apple blade SSD would work internally?

So you can only run via the SD card. Thats a bummer ;-{

Sorry it didn't work out. Someone might be able to fix your socket. In any case please accept the answer at the point.


@danj correct me if I'm wrong.

@kingi, that MBP has USB3 ports, so you can also create a bootable drive using an external SSD/HDD USB3 drive. It won't be as fast as the native drive but if I recall, not all SD cards do their own wear leveling logic, which means you can corrupt your data with an inopportune reboot. (https://electronics.stackexchange.com/qu...)

You may end up having failure again so I'd be inclined to startup the MBP in Internet Recovery mode, connect a clean SSD via USB3 enclosure and install macOS that way.

One other thing, you can also use a usb3 storage key but those too have their own wear leveling and it is not necessarily the same as standard HDD/SSD/NVMe drives. (from my understanding)


@dunc - Go point! I did forget about wear leveling limits of SD card.

It was a good diagnostic approach, not a very good solution. Using an external USB3 or Thunderbolt external drive would be better. But the bottomline fixing would be what I would do a good micro-solder tech with should be able to fix this.

It is possible the motherboard has been damaged. Are you sure the SSD is pushed in all the way and that the battery was disconnected while working on it?
