Readers question: data recovery from the Fusion Drive of a defective MacBook

How do you get photos back from a Fusion Drive if the Mac that contains the hard drives is broken?

A few days ago I got a question from my reader Tony. He wrote the following:

Hello, I have a Macbook 2010, which I equipped with a Fusion Drive according to the instructions from Youtube. On vacation I took a lot of photos and transferred them to the Macbook. Just after that the motherboard went wrong and the photos are not visible on the plates. Luckily, I made a Time Machine backup of the rest of the vacation. Is there a way I can get my photos?

I now have a Macbook 2012 and my wife has one from 2009, too Fusion drive. My first idea was to build the plates into the 2009ner, but then the no-stopping sign came up. Is it because, for known reasons, it still has El Capitan and my 2010ner already has Sierra?

The (simple) solution for data recovery

The "no-stopping sign" described by Tony comes, among other things, when the Mac is supposed to start from a hard drive whose system it cannot do anything with. In this case, the MacBook Tony built the hard drives into was a year older than the model they were originally in. For this reason, the Mac must have expected a different "system" and could not start from the new hard drive.

The hard drives themselves were (fortunately) not damaged in this case, only the mainboard of the MacBook. That is why we can "revive" the hard drives without an expensive data recovery service.

The good news is that you don't even have to convert the hard drives to another MacBook. A Fusion Drive can also be implemented with two externally attached hard drives. Accordingly, the Fusion Drive should also be recognized by another MacBook if you put the SSD hard drive and the "rotating" hard drive in two external USB hard drive enclosures (such as dieses hier) and then plug it into the MacBook. It is only important that they both have to be plugged in, because only then does the Mac recognize that this is a Fusion Drive.

A Fusion Drive can be read out on any Mac if you build both hard drives in a USB housing and plug them into the Mac at the same time.

If you now start the Mac and then open the hard disk utility, you should recognize the new volume there and, if you click on it, see in the information that it is a Fusion Drive.

My reader Tony had already had USB hard drive cases at home and was obviously successful in restoring his vacation photos, because this email came back as a success message at some point:

Hello Jens, Sir Apfelot,

if you weren't knighted, I would. Everything worked as you suggested.

Then of course I made a data backup right away.

Thanks and regards

@Tony: I'm happy that I was able to help you and that you are the happy owner of your photos again! And I'll be happy to accept your accolade if you don't strike so hard. ;)

My recommendation: online backup with Backblaze

Still, a tip for everyone: If your internet connection is reasonably good, I would recommend using an online backup. I've been using it for years Backblaze for my online backup. The advantage is that you have unlimited storage space and you can even back up external drives that are plugged into the Mac. Large photo libraries can also be found here.

The second benefit is that in the event of a house fire, backups stored indoors will be destroyed, but an online backup will remain unaffected. If you use iCloud Photo Library, you basically already have a backup in the cloud. Backblaze However, not only does it back up photos and iCloud documents, it also captures all other data that you back up on the Mac or external hard drives.

And if you're worried that Backblaze will shut down your Mac because it's constantly pushing the Internet connection and the CPU to the limit, rest assured: The App by Backblaze runs in the background on the Mac and only backs up when the Mac is obviously idle. I have not noticed any limitations in my daily work. And that, although my MacBook Pro is already 5 years old.

If you like, take a look at Backblaze. I will soon write a detailed article about the service, which I will link here.

    Hi Jens,
    thanks for the tips, it worked for me. I still have the iMac, but the HHD has one defective. The copying process of the data recovery breaks off every now and then and is very slow, but at least something works :-)
    Do you have any idea whether you can also have a Time Machine backup created from the two disks? That would make recovery with a new hard drive easier.
    Greetings Robin

      Hello Robin! Under System Settings> Time Machine> Options you can choose which hard drives it should NOT back up. If you throw out the two you want to back up, Time Machine will now also create backups of the data on these disks.

    Hi Jens,
    do you have a recommendation for an external housing for a 12 + 16 pin blade SSD from an iMac (late 2013). I am currently looking for a suitable adapter but the information available is very limited. I just always find the OWC Envoy Pro. But there are different versions of it and the compatibility is therefore always very questionable. Do you have another tip?
    Merry Christmas!

    • Jen Kleinholz says:

      Hello Simon! Unfortunately, I have no tip for you. I rarely tinker with the hardware and have therefore never put an iMac SSD in an external housing. : D But maybe another reader has a tip and experience? Merry Christmas to you too!
