Trouble Connecting to External Drive (OWC Gemini)
I have a Mac Mini (late 2014, Fusion Drive) (OSX 12.7.6, APFS) and an external TB3 drive (OWC Gemini) that is not being recognized/mounted.
The Mac Mini lacks a USB-C or Thunderbolt 3 connector of course, but it has regular USB and Thunderbolt 2 connectivity. Attempts to connect to the external drive which is a Thunderbolt 3 drive (https://www.owc.com/solutions/gemini) have been unsuccessful. I have tried an external dock, as well as a direct Apple TB2/TB3 connector. The external drive doesn't mount (and is not viewable using Disk Utility from the Mac Mini).
The OWC Gemini drive does connect OK to a Thunderbolt 3 capable Mac Book Pro 2021 (OSX 14.5). Just not to the Mac Mini (late 2014). The OWC Gemini is RAID1 formatted (MacOS Extended (Journaled)).
Is there something about the setup described which is an issue?
Disk First Aid on the Gemini Drive using the Mac Book Pro 2021 did not identify any issues.
I did a reset PRAM and SMC on the Mac Mini which didn't help. The Mac Mini will connect OK with another external drive (USB, Mac OS Extended Journaled).
As an aside the Mac Mini (late 2014) OS was erased and re-installed, after an attempted Apple OS update from Monterey to OSX 13 caused it to be non bootable. The reinstalled system seems to work ok though, except for the lack of connectivity to the OWC Gemini drive. I don't want to update the OSX on the Mac Mini beyond Monterey, because of what happened previously.
Thanks in advance for any insights.
