I just bought a 2TB Thunderbolt 3 drive and I’m having issues connecting it to my iMac 2017 (on lates MacOS). First it didn’t show up at all, all I got were some notifications of “make sure you correctly unmount the drive before disconnecting it”.
Finally - after some reboots it seemed to stay stable connected - I was able to repartition the disk with APFS and see it in finder.
But now I still get random messages that the drive disconnected. I reconnects again but this seems to be a very unstable connection which I do not want to trust…
Any idea whats going on here? Does the drive not get enough power via the TB3 connector?
