ok so i normal have a 128gb SSD storing my best games and windows 8. i have 2 500gb HHD drives holding everything else i use. i just got a 1.5TB WD green HDD and when i plug it into my computer the 1.5tb drive works but one of the 500gb doesn't get recognized but it shows up in the bios. is this a limitation of windows or my motherboard. or even a psu. im getting a new corsair 500w psu in about a week but right now im using a cheep 500w one that i got from best buy for like $15
