I just built a new computer and did a fresh install of Windows 7 64 bit. During the installation I created three partitions on my 1TB drive.
Onlyy 2 of the partitions showed up, so I went to disk management and found that the third is not assigned a drive letter and is shown as "unallocated space". I tried right clicking on it and formating, but that was not an option.
Also, I have another 320GB drive that no partitions exist on, and the whole drive shows up as unallocated space.
I don't want any partitions on the 320GB, and I want to keep my partitions on the 1TB, but I want to use it (obviously).
