yesterday I brought out my new motherboard that I installed my 2500k into it is out side the case so I decded that I wanted to test this thing out so I grabbed a hard drive which is a seagate 320gb and I used a usb dvd drive so that I could install an OS onto the hard drive. I first tried to install win7x64 but it just wouldn't install it kept saying that I hard corrupted files so I then grabbed an old windows 8x64 disk from way back in Feb ( which I have installed in VM on my main PC ) and when I tried to install onto the same hard d rive I received the same message. I then tryed server 2012 this time I recieved a message saying that I could not install on the hard drive because the format was different and it wouldn't let me do anything with the hard drive. I turned off the power to the motherboard , unplugged the hard drive. the connected it to my main PC and reformatted the hard drive. then re connected it to the motherboard and tried again. This time the install started got all the way to finishing up then stopped with an error saying that the files are corrupt. see my brother had similar happen to him a few months ago, but it did turn out to be his hard drive going back, took him something like 8 install/formats to get the os
