Another option that might help with what Phil has been suggesting ... if
you want to keep them as portable backup drives (not a bad idea) get a
couple of new drives to stick in a computer, dd or ddrescue the
partitions across, and fix it on the computer in order to do your
recovery (I note that USB seems to have been shuffling your drive order,
making re-assembling the array difficult!).
Amazon have been pushing the Hitachi 7K4000 drive at me, which is a 4TB
drive apparently certified for raid, for only £70! Two of those will
enable you to recover your array, back it up, and then you can decide
what sort of raid or whatever you want to make from those drives. Four
of them would give you a lovely 8TB raid-6 as a store for whatever you
want ... drooolll....
Cheers,
Wol
