Don't make same mistake I did and trust the the information which 3.1 gives about the hard disk. I trusted, and few weeks later when I was doing new partitions I noticed that the OS saw only 8GB drive instead of 40GB what it should have been.. grr. So I had to re-install the RDB on it and destroy everything I got together at that point.
Anyways, that was my bad for not checking it at the first place.
