Can I control what Time Machine Backs up?

I bought a 2TB external drive last night and set up my Time Machine to back up my iMac. I have up to 5 external drives hooked up to my computer. The first backup failed saying I needed more than 2TB of space. I noticed one of my external drives was active too. So I stopped the backup and ejected each of my external drives. When I started Time Machine again, it said it only needed 1.85 GB! Thats more like it!!! When I clicked on the options button and removed all the external drives to NOT be included in the backup for some reason it was still backing up those drives. I am not sure why.


So moving forward what is the best plan of action? Do I turn the TM off when I have those external drives mounted or vice versa and eject all my external drives and leave TM on?


Thanks!

iMac, iOS 5.0.1
