How to fix: OWC Aura Pro X2 SSD not recognized

Technical problems are the worst. I tried to prepare my Apple Mac Pro for selling it on eBay. Obviously I wanted to delete all my data on it, but I couldn’t figure out how to erase my regular SSD disk and do a fresh installation of Big Sur.

The problem was that in Disk Utility the SSD (OWC Aura Pro X2) was visible but I could not remove or erase the SSD itself or the according partition. Of course I tried to reboot and use the Option+R disk utility. Unfortunately the OWC Aura Pro X2 didn’t even show up there. I tried a lot of things but nothing worked.

The solution is actually simple, but it’s easy to say after hours of trying a lot of things.

You need a bootable USB drive with Big Sur on it. Then you start Disk Utility from there and suddenly OWC Aura Pro X2 SSD shows up. Now you can delete it and/or add a new partition.

To prepare the bootable USB drive I’ve used the free version of Disk Drill (https://www.cleverfiles.com/). There is an option “macOS Installer”. It’s pretty easy and self-explanatory. Generate a bootable USB drive with a macOS Installer. Then you re-start your mac by pressing the OPTION key. Choose the USB drive as the boot drive. There you will find Disk Utility again and now it will recognize your OWC Aura Pro X2 SSD.

You can now erase, re-partition, remove, format and repair your OWC Aura Pro X2 SSD easily – and most importantly for me, re-install a clean Big Sur for selling an Apple Mac Pro on eBay.
