Hypo, you can download demo version of Search&Rescue from
www.pcrepairman.com;
so you will see at least what is recoverable.
This proggie will show you most exact evaluation (better than EasyRecovery, FinalData etc.)
You need to boot from another HDD with good Windows, of course.
And don't try to change anything on crashed disks, don't remove Norton also. Your odds are the best if you don't write even a byte to crashed disk. Files/folders deletion is updating some sectors, so it is writing to the disk also. Don't do it!
