Disable Time Machine prompts for external disks

This certainly isn’t a new thing but I haven’t had a need for it until just recently. I moved my lab machines to Leopard and now every time you plug in an external hard drive it asks to use it for a Time Machine backup. That gets annoying fast. Use the defaults command in Terminal to shut it off. I used Apple Remote Desktop to send it out to all my machines at once.

defaults write com.apple.TimeMachine DoNotOfferNewDisksForBackup -bool YES
