Pretty sure cloning isn’t going to work. I put a new drive in mine after a failure. There is a thread here about doing it. It’s worked out well, after all it is still up and running. I considered a new NAS but liked the challenge the MBL was presenting me with so I did a 3TB WD Red replacement, which was the same drive it came with. HERE is a link to the thread. It’s long but make sure you read through the whole thing for trouple shooting if you do a replacement and have an issue. I dunno if nfodiz (the original poster of the thread) is still around but he helped me when I had an issue doing mine.
