If you do not have a second hard drive, you will at least need a second computer. The following methods may work:

  1. If you are running MacOS X: Start up the computer with the Bad Device in Firewire Target Mode (hold down T at startup) and connect it to the second computer using a Firewire cable. The second computer will see the Bad Device as a Firewire volume. (If the drive doesn’t appear on the second computer when you launch VirtualLab make sure you are using MacOS X as MacOS 9 cannot access Firewire drives that do not mount) 
  2. If you are running MacOS 9: Connect both computers over a network and install VirtualLab™ on the second computer with the Good Device. Boot the computer you are trying to recover with the Bad Device (if it will boot) and connect to the second computer via File Sharing (Appletalk or Appletalk TCP/IP). Then navigate to the VirtualLab application on the shared volume and launch VirtualLab. When asked to save the Session File and Recovered Files, save them to the shared volume.
