Well I think I made a huge mistake so this is my last resort.
I initially added all of my drives. I got a message saying unmountable: Unsupported partition layout. All of the drives that I added were empty with the exception of one that had pictures, movies, software etc. As soon as i started the array it started writing to the two parity disks. I wasn't sure if this was reading from my 2TB drive or not. I let it do its thing for 8 hours and it finally completed. I stopped the array, unmounted the 2tb drive, and then restarted the array. It gave me a message saying the drive was missing but I can emulate it. I clicked yes start the array and then clicked format drives assuming it would not format the 2TB drive as it was now unmounted. When I try to add it back to the array it says that all data will be overwritten when array is started.
Is there anyway to recover this? Did I actually delete the data?
