One of the huge amazing features of Leopard that people won’t shut up about is Time Machine. And, ok, it is really cool, and hopefully it will get people backing up their systems who never have before.
On episode 98 of the Macworld Podcast, one of the guests/hosts made the comment that Time Machine would not back up their external hard drives along with the internal one.
It will, you just have to set some preferences. I found that on my system, Time Machine put all my external drives in a list of disks NOT to back up.
Here’s how to change that. Open system Preferences.

Click on the Time Machine Icon to get the Time Machine Preferences.

Click the Options button. You’ll see a list of drives NOT to back up. Highlight the drive(s) you DO want to back up, and click the minus sign at the bottom of the list. Woohoo!
