Format a RAID drive

[philwright]

Hello,
I bought a used hard drive which had (has) a RAID configuration. I tried in win 7 manage/disk management to format the drive. Right clicked it, but format is not an option. Will someone remind me how to do this from a command prompt?

diskpart, list disk #, select disk #, clean, create partition primary, select partition 1, format fs=ntfs, active, assign. done
