Hi Guys so got a new HDD from a seller, which i trust. It is a Western Digital Caviar Black 2TB 2002FAEX. I read this post:http://www.tomshardware.co.uk/forum/265764-32-guide-installed-disk-system because my OS (windows 7) doesnt detect it. It isnt detected in BIOS and a Linux Live Stick didnt detect it either. I tried switching SATA ports, switching SATA cable, it is plugged in and running, i can hear the spinning. My mainboard is a Gigabyte Z77X-D3H. What to do now?
