As far as I know, Nvidia makes graphics cards, not hard drives. Are you sure you checked here:
@ abrody - They usually do not restore or backup your data - but that shouldn't be necessary; most people do have bootable clones or TM backups (or they should).
I've restored a clone to an internal; if an OS is installed on the new one, simply use TM to restore or, upon first setup, use Setup Assistant. I will most likely simply boot from my external clone, wipe the new internal drive, and clone my system back. That would be my preferred method.
I also received an email; I will call Apple to ask if it can be done in house since I have Applecare and in home service is included. If I have to take in the machine, I don't know that I would trust them with my SL install disks - I'd need to talk to them about it because I don't feel comfortable giving my disks to a repair place.
For anyone: remember to wipe the disk before it is replaced; you have no idea where that disk will go and who will have access to it......
Edit: I see you posted your HD info and it does say Nvidia - that is strange, especially since your hard drive also starts with ST which is Seagate.
