Sorry, just to clarify: I wasn't formatting a drive at the time that I lost the data. In general the process I have been using is: format a drive so it is fresh, add it to the pool (without duplication or scheduled balancing) and then copy data into the pool from another drive, freeing that drive up in the process. I would then format that drive and add it to the pool etc. I had just added the third drive to the pool and was copying data from a fourth drive (not in the pool) into the pool and that is when I appear to have lost all of the data. The Folders that I had inside the PoolPart folders are now reporting Owner as "unable to display current owner". So something strange has completely ripped the pool apart here. I'm still struggling to put together the pieces. Windows may have also downloaded/installed some Windows Updates during the night (great Windows 10 feature that I can't seem to prevent) but somewhere along the way the combination of that, the copy process and the pool it has managed to wipe 6.5TB of data. I really want to use this product but I need find out what happened here and make sure it doesn't happen again. Out of interest does anyone have any experience of some good free data recovery tools for files larger than 4GB? I have used Recuva to scan the drives but it reports all files over 4GB as unrecoverable. This seems to be a limitation with the way that the NTFS deletes files over 4GB but there must surely be a tool out there that can recover them.

I think I just had something very similar happen and I have lost about 6.5TB of data. I have been formatting drives and adding them to the pool and then copying data into it. I had just added a new 4TB drive to the pool (total 2x 3TB and 1x 4TB) and I was copying data in from another 4TB drive. The files were not yet duplicated and balancing was turned off as I did not yet have enough capacity to do it. Sometime during the night the copying stopped due a "permissions" issue. When I checked it this morning I saw the copy had failed and the Pool was now empty! The three disks that made up the pool were all mostly empty. Trying to access the pool folders on them resulting in access denied errors. I have run some drive recovery software on the drives and most is unrecoverable as it says the data is no longer on disk. Some can be recovered but recovering them appears to strip the directory structure and so I'll just have all my files in a single place. Plus it doesn't recommend recovering them to the same drive. I do have some of the data in another place because I was in the process of putting it all in the pool and removing duplicates before enabling pool duplication. Luckily I hadn't managed to finish or I could have lost the whole lot. I need to know why this happened because at the moment I have lost all faith in the software which is a shame because other than this it appeared to do exactly what I wanted!
