I was only using the enclosure to test the drive while connected to my main rig. I'm not planning to leave it in there once the testing is done. I'm not one to buy a drive and put data on it right away. I test first then once it is proven to be good, then I put data on it. When I saw the slow data speed connection, I suspected the enclosure, never used it to test a drive before, so I moved the drive to my NAS box rig where I could connect it directly and remove any doubt about something in the middle causing problems. When I put it on the NAS box, I used the same power cable and data cable that I use to update my backups and it works without error. I don't see how it can be the data cable, power or mobo in this case. All those work fine when doing backups. It powers 4 hard drives in that setup.

The only other drive connected is a SSD for the OS. As mentioned above, this is what I use to connect a 4 drive setup for my backups. I even use the same power connector. I also used one of the same data cables. I might add, I just tested a 16TB drive and it worked without error of any kind. It's in the safe while I figure out which drive, 16TB or 20TB, is going to be added to my backup drives and which will be added to my main rig. So far, this is the first drive I've ever seen this 'slow to respond' message with before. Since I've never seen it before, curious as to what it means exactly and is it normal? Searching didn't help. Some claim kernel, others claim something else. As soon as this test completes, another few hours to go yet, I'm going to power cycle the drive again to see what it does. I may cycle it a few times to see if it is a consistent problem as well. Dale :-) :-)
