If you have a Maxtor or Seagate drive connected to your system (even via USB) then download the free DiscWizard tool from the Seagate website.
You can always use DriveImageXML to do this as well. Good app that.
If you're in Vista, make sure you run it as an administrator and turn off UAC when you want to use it.I'm gonna try this, thanks for the link, all the others are huge by comparison. ta
