If it's exactly the same size, then yes. Keep in mind that you don't
copy files but the whole hard disk - including boot sectors and the
partition table. And, of course, if some of your data is already
corrupt, you are going to have a corrupt copy as well.

BTW: if I were you, I'd take the time to plug one of the drives on the
secondary ide controller (if your machine has one). Copying between two
IDE devices on the same controller is awfully slow.

Dunno.
