FYI, you can directly access the hardware by obtaining a level 3 volume lock, then a level 1 volume lock, and then using a VXD to directly manipulate the raw driver interfaces. It's actually pretty trivial, even for Windows programming. C.v. "Partition Magic" for one example of a product that does this.
