That is intentional. /dev/SDA is a Seagate and /dev/sdc is a WD. This
way I reduce the chance of a simultaneous failure, like we had at the
BLU last year where all of our drives were the same MFR and lot #. 
Actually, somehow Fedora partitioner set up /dev/sda1 to end not on a
cylinder boundary.  I was unable to set up /dev/sdc1 exactly the same.
If I start from scratch, they will be the same exact size.
