Make sure the LBA mode is enabled for large capacity support. A full description of Logical Block Addressing can be looked over at Logical Block Addressing
to understand what that is for.
Often you might by chance have looked closed at the total amount of drive detected by the installer and simply pressed the install button while the partition size was smaller then the total amount shown. A 3rd party drive tool known as the Gnome Partition Editor has a live for cd version called GParted live for cd available free of charge if you have a cd writer or dvd burner available to use.
The documentation for GParted with screen shots can be easily followed at GPARTED DOCUMENTATION - GENERALITIES
Personally I use GParted here first to create any new primaries and then see them formatted by the Windows installer for the version going on. The 0.3.3.0 and 0.3.2.0 releases half way down the page at SourceForge.net: Files
are the platform independent versions for being able to create, delete, and of course what you need there resize partitions.
