I think you're missing some pieces. Also I think you should learn how
assembly language works before trying something like accessing hard
drive information.

For basic information on how assembly language programming works, and
how it interacts with the rest of the operating system see my book:

For information about getting hard drive information under Linux I would
check out the source code to fdisk.
