new hdd to factory state - problems

[thinky]

I just got a new 7200 rpm hdd, and I want to initialize it to factory state using product recovery discs that I have created earlier. However when R&R asks for the product recovery discs, none of the discs work. It gives me an error saying its incorrect disc. Can any one suggest a solution ?
Thanks

Don't select the option: yes when it asks is it IBM disk. Click NO and you are ready to go.

There is only 1 question and 2 options yes and no.

Q)Is this disk from IBM?
Click NO

thanks, I have been so stupid, I confused the supplementary recovery discs and product recovery disc. Thanks again
