HDD showing in Device Manager and properties but not in My Computer!

[phalicopter]

Hi, it's a new build and happening when i plug in with a sata II cable from my old computer the same drive is alright with a new Asus sata III that i got with the motherboard. My motherboard is Asus Z87-Pro. Better still here's my parts list: http://uk.pcpartpicker.com/p/sFD9FT

It happens on any of the hard drives if i swap the cable round i tried that first. I only have 4 sata III cables. Like i said the computer recognizes the hdd it says "Device working properly" in device manager but it isn't giving me the storage in my computer!

Anyone help please?

Cheers
