While setting up a new f6 424 max I transferred my data from a PC to a new pool and volume.

Then I formatted and transfered the old hdd from the windows pc and added it to the nas pool. After synchronisation the whole pool and volume disappeared. All data gone. The 6 drive still register as healthy but the is no pool or data.

Did you create the RAID on the F6-424 Max and then add the HDD from the PC to the RAID?
Guessing there was probably an HDD failure that triggered the problem, but not ruling out other possibilities.
