The partition is just a map, if you can re-create the partition
exactly the way it was before, the data should still be there if
it wasn't overwritten.

But as far as I know there isn't a backup stored of the partition
table, if the disk is exactly the same as the other member, then you
can try duplicating the partition setup using the first disk as
a guide.

I don't know whether or not it will help restore a RAID 0 set,
but may be worth a shot since the situation probably can't get
much worse.
