You need to identify where the parity blocks are at each drive to work out the direction and length of it, also you can identify 2 disks with XOR at the same position then these are from opposing RAID sets. Sometimes you can use differentiate which set by looking at the pattern of data but additionally there may be some metadata at the ends of the disks that can differentiate the two RAID5 sets.
