Hi, I am not sure what the solution is (but there is one, search the forums) but I think I know what the problem is:
Your old drive is an IDE drive (or PATA as it is now called, I believe) and your new drive is SATA.
There is lurking in my memory a glimmer that someone had this problem a couple of years ago and had to change a script to reflect this - it all worked afterwards.
Sorry I can't be more specific.
Cheers
Ian
