Thanks for all the help chaps.
Got it back up and running off the new hdd, with the old one as the slave and recovered all the files I needed from the old hdd and have now backed them up too !.
I ended up using the NTFS file recovery software as suggested by Mr Optimistic, cost me £68 for the software, but a lesson has also been learnt too !!.
It was pretty good, took about an hour to find everything on the old hdd and was really easy to use. Just selected the file I wanted, then saved it onto the new hdd then backed up to dvd.
Going to get an external hdd too to store files on from now on, and use the internal to just run programs from.
Thanks again
