can I add an extra 1.5T hard drive to my XPS 420?

Yes you can add another drive but the specs say only up to 1 TB. You should be able to look up your specs in your manual, but here is an online link:

That assumes you have not added one already - you have 2 HD bays. You might also double check to confirm you have the free PSU cable and open mobo SATA connector - but these are usually not an issue as long as you have not already used the extras that are provided.
