I cloned my failing hard drive (a 160gb) to a new one (500gb). The installation seemed to go smoothly enough (it was my first time though) as it just required me to stay grounded and remove about 4-5 screws. When I loaded the PC up it wouldnt start the first time so I had to a Windows repair, which didn't seem to do anything except now it worked (it said it failed or something). I then had an issue with Windows 7 claiming to not be genuine although for one reason or another that stopped. Now my issue is that I am unable to access the additional memory of my new hard drive, I am able to access the cloned portion but not the rest (about 316gb). Any help would be appreciated, my PC is a Dell Latitude E6400 if that helps.
