Motherboard, weird problems. Help please

[TheCenturion]

Okay, I've just built a new system (build log in sig)

Motherboard is Asus P6X58D-E
A couple of problems, I think they're something to do with the motherboard. I've got 4 things plugged into the 4 Sata ports.

Sata 1- intel ssd
sata 2- Sammy F3 1tb
Sata 3- Sammy blu ray drive
Sata 4- some sata that came attached to the case (no idea what it's for )

Yet, in the bios, it says:

Sata1- Not detected
Sata2- Intel ssd
Sata3- Sammy F3
Sata4- Sammy Blu ray

Nothing is connected into the 6gb/s ports

In windows, my F3 isn't showing up in My Computer, only the ssd is showing up. Yet in the bios it actually detects both HD's

Also, when I set the ssd as my primary drive, and the sammy as my secondary drive, the system doesn't boot up. It just says 'No hard drive detected'
It only boots up when the sammy is set as the primary HD and the intel as the secondary HD

Help me plz

Thanks

EDIT: The samsung f3 is detected in device manager, but just doesn't show up in My Computer

Hi, I've done some shifting around and now this is what it looks like in the bios:

1. Intel ssd
2. Samsung f3
3. Samsung bluray
4. [not detected]

It's still not coming up in My Computer though

Hi, thanks mate. I went into disk management and it was unallocated so I added a 'simple volume' and now it's displaying in My Computer. Thanks
