when I built my PC I used a 500GB harddrive, although it only says it is 127GB, I have tried re-formatting it and searching for the rest of it but to no luck. So I thought i'd take a short cut and just buy a new hard drive so that's what I did, I bought a 1TB hard drive earlier today, but now it is only showing a maximum size of 337GB. I am not too bothered about trying to recover what is on my local disk I just want the full 1TB on drive D.
