One of two RAID 1s is not recognized in Ubuntu 13.04
I have a 256GB SSD (Ubuntu/Win8), and two 1TB drives in RAID 1.
The problem is that I just recently added another two drives that are 4TB in RAID 1 but they aren't detected in Ubuntu as one drive but separate.
I know it works because Windows detected my new 4TB RAID 1 just fine, here's a screenshot via one of the raid disk utilities that came with my motherboard (fakeraid).
Also here's the fdisk information for my setup:

This doesn't look like a partition table
Probably you selected the wrong device.

How can I get Ubuntu to recognize my newly made 4TB RAID 1?
After much research it seems fakeraid doesn't support drives bigger than 1TB~. I was forced to buy a raid controller which worked like a charm. Thanks for everyones' input and time.
