Try an Ubuntu live CD or similar. If it doesn't see the external drives, there's a reasonable chance you can modprobe something or enable hotplug support after you've already booted. Alternately, can you alter your primary system's MBR to alleviate the conflict, and then get in and fix things properly? -- :wq
