I have the Anker elite 13 in 1 TB doc. If I connnect an external HD, such as WD Elemets 4GB USB 3.0, or the Segate Expanstion 4TB USB 3.0, neither appear in the disk utilities nor finder (with external HD display enabled in preferences). However, If I plug either directly into the Mac via usbc-usb3 converter, they both work.
Im using an M1 mac with Big Sur. As the mac only has 2 ports, not being able to use the dock means I cant connect 2 drives.
Any ideas?
I have tried different cables, rebooting etc.
