I am, it's a USB2 port with a USB2 flash drive. I have a Gigabyte M97M-D3H motherboard, i3-4150, 16GB ram, 6 3TB WD Red. This was originally a FreeNAS server that I am converting over to UnRaid. I have reloaded the drive mulitple times and have used 3 new 32GB SanDisk drives and getting the same error on all 3.
