Hi...I have a Western Digital External harddrive, pro series, 1 TB and it has two physical drives in it's box, and when I hook it up to my Windows PC and transfer files it seems to go to one, and then on my mac it goes to the other. And I can't seem to access the windows from my mac and vice versa. I'd like to access the files I put on there from my windows computer, on my mac. Anyone know how to do this??
