Your question is unclear. There is no main "HDD passcode" of any sort. There is usually a Master File Table (MFT) or a Master Boot Record (MBR) on most hard drives. There are utilities to clear those. If you would like to format your entire hard drive, you can use the Windows command line program "format" to clear your entire drive (and all of your programs and files as well).
Please revise or clarify your question in the discussion page so that we can be of better assistance.
