hard drive not recognised

[the_broken]

I got a new hard drive today, WD black caviar sata 3 6GBps, i installed it and turned it on and it didnt not recognize, though it was in intel storage management program, so i had a look and couldnt see how to get that onto my computer instead, so i went to the bios o see if it was there, it was not, so i changed ACHI to disabled, raid etc, and still didnt not register, now it wont pick up in the intel program either

i really dont know why its not in my computer

the system i have is:

Asus Maximus IV Extreme-Z Intel Z68
Intel Core i7-2600K 3
OCZ ZX Series 1000W '80 Plus Gold' Modular Power Supply
G.Skill RipJawsX 4x4GB DDR3 1600MHz
Corsair Force GT 120GB 2.5" SATA 6Gb/s [OS installed here with all programs and drivers]

if anyone can think of something please let me know
