OWC Envoy Pro SSD not being recognised

My Late 2013 MacBook Pro died and Apple’s assessment was logic board failure. I now have a MacBook Pro 2019 and I want to get the data from the SSD on the old laptop.

I bought an OWC Envoy Pro with USB and I put the old SSD in it. Connected it to my new MacBook via an Apple dongle and… nothing. The case has a light that flashes at a regular interval (~1s), but nothing comes up.

I haven’t been able to find anything around what the regular flashing light means.

My old MacBook was running Mojave, and the new MacBook is running Catalina. So it should have the right firmware to read the drive.

Terminal command “diskutil list” yields only the internal drive, so does Disk Utility UI.

System Report doesn’t show anything either. The only thing I find suspicious is that under “USB”, it only shows the dongle I use: “Apple USB-C Digital AV Multiport Adaptor”.

Is it because of the USB to USB-C conversion? What am I doing wrong?

Thanks in advance!

Do you still have your old system?

If you do, put the SSD back in and plug in the MagSafe charger.

Now lets give this a try! Restart your system but press the T key are you able to get it to come up in Target Disk Mode? Understanding the Applications for Target Disk Mode

If you are then we can try to leverage your old system to gain access to the SSD via a Thunderbolt cable to Thunderbolt to Thunderbolt3 dongle on your new MacBook Pro Apple Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter. If still can’t gain access then the SSD was really the problem with your older system.

Thanks for the quick reply Dan!

I do have the old MacBook but its logic board died, and it will not power on at all. :(

Then you may have either a bad OWC adapter or the SSD its self also failed.

The problem here is APFS! If you had HFS+ then I could have pointed you to a data recovery app to try to salvage the data. Sadly, there is none! None of the 3rd parties have been able to get the needed information Apple to create any drive tools.

Nooo... I have emailed OWC with the same question. Will report back what they say.

完成的
