Backing up more than one drive

Hi, I am a new user of this exteranl HD and I am wondering if it is possible to back up more than one drive. When I did my first back up it did my C drive, but at my workplace we also have an H drive to keep documents on. I would like to bak that up as well. I would apprecaite any information someone could give me.

If you are using the new SmartWare, then you might be able to back up an external drive, if it allows you to choose it when you are creating the backup.
