10.5: Disable the 'use this disk?' Time Machine dialog

Contributed by: meancode

This hint will be useful for those who use an abnormal amount of removable devices on their personal or work computer, or those who deploy 10.5 in a multi-machine environment. When you connect such devices, Time Machine asks if you'd like to use them for backing up. You can disable that warning -- just launch Terminal, and paste this line, then press Return:

defaults write com.apple.TimeMachine DoNotOfferNewDisksForBackup -bool YES
Time Machine will no longer ask to use the devices you connect.

[robg adds: To reverse this, you can repeat the above command with NO at the end instead of YES.]
