How to calculate the sector address of the unpartitionable space on harddisk?

I am so sorry for post this question on OSR’s NTDEV list. Because the focus of this list is about NT device driver develop. However,I think storage device driver expert may have the answer of my question.Thanks a lot.
You can use Winhex to view unpartitionable space. Windows do not use this space anytime. Even the harddisk have no partition,the unpartitionable space is also existing.

How about posting the question to the NTFSD list, which is a list for
people who develop file systems?
