Adding a third hard drive?

[masona3]

For the longest time, I've had an 80GB "main" drive and a 250GB "storage" drive. My wife just bought me another 250GB drive for my birthday (running out of space for things... really needed it) but I'm unsure of how to set it up. I need an IDE controller card, right? These are standard IDE hard drives... nothing special. They're the WD Caviars, all three of them...

Any help would be appreciated... and, of course, I'm looking for the cheapest possible solution.

Do you have optical drives on IDE as well? If you've got a free IDE port on one of the cables you already have, set the new drive to "Slave" with the jumpers on the back, and make sure the existing drive is set to "Master" (not "Single").
