I recently got a new HDD and added it to my PC. I now have 2 HDD (1t each) which when I formatted and installed windows 7 home premium, divided into 2 partitions each. I can see both HDD's in my bios and in the device manager (it says they are working properly) but in my computer I can only see the first partition of the first HDD. the other partition as well as the second HDD cannot be seen. What can I do? I have already tried every combination of SATA arrangement from my motherboard and still nothing.
