|A dynamic disk is an extension, if you will, of the primary disk. As such the data is tied to the original disk. You reformatted the original disk. So if it was a dynamic disk testdisk may not work. |
Another method to recover the files would be to use a live version of Linux.
Knoppix is one that installs to an runs from ONE CDR/DVDR. You boot to knoppix and it may be able to find the files on the second drive. You can download Knoppix from the link below. You will need a fast connection and burning capability.
Did you try accessing the second drive before any service packs were installed?
