Thank you so much for doing this. Had an easier time with the 2 small clips than the big one. Definitely try the drive before you put it in. The first Seagate 6TB Ironwolf didn’t work when I tested it out so had to exchange it. Would not have been happy had I installed it and then discovered it didn’t work. One odd thing was that when I tried out the old disk in a different housing it seemed like it was working so not sure what means. Thought that perhaps there might be a power supply issue but so far not. Again thank you.
