Windows 7: Clean command on 3tb disk containing OS?

Clean command on 3tb disk containing OS?

I recently did a new build and did my research a little too late regarding Windows 7 not "liking" 3tb drives formatted with MBR. So I decided to move my media from my previous 2tb drive to the available 2tb partition on my new 3tb drive, reformat the 2tb drive, reinstall the OS on that drive, and am now moving the media back to the 2tb drive in order to completely clean the 3tb drive (wanting to make that my new dedicated media drive). Will the clean command from the elevated command prompt clean a drive and all of the partitions/unallocated space on a drive that contains system files and an OS, allowing me to reformat in GPT giving me the full 3tb available? If not, how do I completely clear this drive and make the full 3tb available?
