Howdy, I ran up on a couple deals. I first bought a 16TB drive which worked fine. Then I saw a deal on a 20TB drive. I first put it in a external enclosure and connected it by eSATA cable to my new rig. I got this in messages.

Maybe the enclosure limits the speed??? What concerns me with the NAS box info, the first part about slow to respond. Is that normal? Also, is it likely since it works on the NAS box at full speed that the enclosure is causing the slow down or is that slow to respond a possible cause? I ran the conveyance and short test and it passed both tests. I'm about to start the long test. I figure that will take a couple days, or close to it. Looking for thoughts on whether this drive has issues. I might add, the company I buy from packages their drives to survive about anything. Drive is put in a tough plastic bubble wrap made just for hard drives and that is placed in a box. They then wrap that box in large bubble wrap, like any of us can buy, and put that in a large second box. I can't imagine the drive being damaged in shipping. Oh, when I get a new drive, I first watch messages to see how it connects. Then I run conveyance test, short test and then long test. If it passes all that, I then add it to a LVM drive set or use in some other way. I'm thinking about buying another spare 20TB. Good deal at just over $200 and current drive has only 2 run hours. O_O Thoughts on the above info? Anyone seen this before? Is this drive perfectly fine? Need to return? Thanks. Dale :-) :-)
