Have you tried the Live CD yet?

I ran into a very similar recovery a month or two ago.
The chkdsk /r command failed and from a bootable ERD
cd, the NTFS partition had a similar 'raw' format, 0 bytes
used, 0 bytes free. Booted to an Insert cd with a usb
drive, mounted both the hdd and sda and recovered
everything. It was about a 3 hour job, but well worth
it.

Funny how the drive was mountable in Linux and all
but invisible booting to a Windows/ERD cd.
