Ok, so i have an old hard drive of 150GBs, so i wanted to use it as hard drive for my windows and 500GB hard drive for games... Now the drive of 150GBs was lying around for a year and i am not sure if its faulty. I plugged it in my pc and it seams like its working fine, i have a few games on it, but I remember that i was trying to install windows on it and it didnt work, tho it could be that my cd was bad. My question is how do i know that its completely fine and that I can use it as my windows hard drive?
