Time Machine question

[carrollf]

I have a 500Gb internal drive in my iMac, another 500Gb external drive (USB) and a 1Tb Firewire800 drive. Can I set up Time Machine to back up both my internal 500Gb drive and my external 500Gb drive to my external 1Tb drive?

Yes you can. Just go to Time Machine preferences, options, and delete the small external disk from the list.
