So I just added a new WD 10TB HDD to my system and precleared it. After a succesfull preclear my two Seagate 8TB HDD's that were attached via a USB dock and until now working perfectly, had the red x next to them and marked as being emulated. I tried a reboot but no change. I powered down and restarted also without luck. Thinking the dock might be faulty I tried another dock, it didn't recognize the drives at all, marked them as missing. I reattached the original dock after checking that it was working on another computer. On reboot the two drives now had a blue square next to them. Couldn't find much info on this apart from UnRAID thinking two new drives had been added. As I had two parity drives I thought that starting the array would rebuild the two 'new' drives so I did so. UnRAID displayed 'Parity Sync/Data-Rebuild' and a percentage in the status bar so I was optimistic. The notification said that Disks 4 and 5 were not ready and contents were being reconstructed. About 54 hours later, those two drives now appear with a green circle but with the message 'Unmountable: No file system'. I haven't formatted them yet. Have I lost 16TB of data? It seems what UnRAID did is recalculate parity for the other three drives that were still OK, so I might not be able to restore my lost data if it's no longer included on the updated parity drives. What should I be doing now? Any chance of recovering anything? Screenshots taken throughout the process are attached. Running UNRAID 6.4.1

I recently added a second parity disk which is 10TB. My primary parity is 8TB. All other disks in the array are 8TB. I've now decided I need the extra storage so want to make the 10TB HDD parity 1 and use the original parity disk as storage. They both have recently checked valid parity data. Is there any way I can do this without rebuilding the parity? My idea was to use new config and change parity 2 to parity 1 and add the original parity 1 disk as a new array disk. All the other disks would remain in their same slots, but this will rebuild parity.

It worked. Thank you.

I've recently moved my seven drives (6x8TB HDD + 1TB SSD) from my HP N40L to a Lenovo TS140. I'm on unRAID 6.4.1. On the HP N40L two drives were connected via an external dock by eSATA. Unfortunately the Lenovo doesn't have an eSATA port so I've connected those same two drives in the same dock with a USB cable. My problem is that those two drives are showing up as 'no device' but listed in the appropriate dropdown menus with their serial numbers formatted sligtly differently eg. original format of Disk 4 was: STAS0002-1NA***_Z*****EB - 8 TB whereas in the drop down menu it shows as: ST8000AS_002-1NA***_Z*****EB - 8 TB (The number/letters iv'e asterisked are identical in both). The same goes for Disk 5 and it's drop down menu. When I select the differently formatted drives in the drop down it shows 'wrong'. I think this may be due to the new connection method via a USB cable instead of eSATA. Anyway after a bit of research I think I may just be able to do a new config and assign all the drives to their correct slots and not lose any data. Can someone please confirm this and any other consequences of doing this or suggest an alternative. Thanks.
