After updating Catalina (10.15.6) my lightning port (iMac 5K) is not detecting Lacie external drive

Hi there,


I've updated my iMac (Retina 5K, 27-inch, Late 2015) into macOS Catalina (10.15.6).


Since then, my LaCie Rugged Thunderbolt (USB 3) external drive is not detected. The light from the drive turns on when plugged into the iMac, but I can't see the content on it.


When I use the USB cable, the drive is detected and working.

Before the update, the thunderbolt was working just fine.


Did you experience something like this?

If so, did you fix it?


Thanks.

Angel

iMac 27″, macOS 10.15
