You should be able to see the relevant information here:

It appears to be related to the use of a Host Protected Area ( HPA ). 
Both disks are the same size, but one has some space reserved as an HPA. 
  The metadata in that disk reports its size as reduced by the size of 
the HPA.  The metadata in the second disk appears to report the size of 
the first disk in its entirety, not respecting the HPA.  Because the 
metadata on each disk disagrees, their checksums were different when 
created which lead to them showing different values for family_num, 
which causes dmraid to identify each disk as belonging to different 
unrelated raid sets.

So it appears that the bios has a bug that caused it to generate 
incorrect metadata when the raid set was created, yet the windows driver 
appears to ignore this inconsistency and operate anyhow.
