Hello everyone, I ask for help I have a 20gb hard drive, model indicated above, the bios sees the ability Total10 gb instead when the hard drive is 20gb. also operating systems like windows xp or windows 7, see 10 gb, I do not understand why? the motherboard is a gigabyte ga-8st667 .. this is a hard drive that I added and the hard disk that there is now a 320gb that is not partitioned and sees it for its real size .. I tried to see even in the jumper if there was any limitation as limiter cap but nothing. Can you help me?
