You can mount them under Linux, but you do need mdadm and btrfs-progs installed. Something like

If it is RAID-1 you can certainly reverse the drives (and you can try mounting in linux with only one, since they are mirrored).
I believe that is also the case with RAID-0, but I've never tried it. Perhaps JohnCM_S Marc_V or another Netgear mod can confirm.
