Thunderbolt 2 to USB 3 .1 gen2 via Adaptor

Hi:


I have an (oldish) iMac (Retina 5K, 27-inch, Late 2015) with Thunderbolt 2.


I just bought a LaCie d2 professional 10TB external harddrive that has a single USB 3.2 gen 2 connector.


I have an Apple Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter:

The drive is externally powered.


Problem: when I connect the iMac to the LaCie via the adapter nothing happens (no blue light when clicking the front button).


Yet when I connect my new M1 MBP to the drive directly with a Thunderbolt 4 cable all works fine.


Does the adapter not work when going from Thunderbolt 2?


Thanks!

Your machine supports USB 3 which is quite fast! You did not state how you intend to use EHD, for most day to day work USB is plenty fast. If you are a video or music professional then yes, Thunderbolt would save you time (which = money) and you should use that. However I am guessing you are not a video or music professional otherwise you would be using more up-to-date hardware.
