This is a question to all the System 7.0 beta testers out there.

When System 7.0 is released, I want to be able to set up an external hard 
drive completely configured to run 7.0 only.

I also want to keep my internal hard drive configured for 6.0.4. The reason 
for 2 complete configurations should be apparent. This setup would give me 
the ability to run my own real-world tests on 7.0 and see if it is reliable 
enough to implement at work.

Would there be a problem with having these 2 hard drives hooked up 
simultaneously? I want the ability to drop back and punt, so to speak, to 
System 6.0.4 when I need to get some work done and not have to disconnect 
the external hard drive to do so.

I have read many of your posts concerning a hard drive that has been 
"touched" by system 7.0. Am I in danger of some unexpected & bizzare 
behavior with this setup, or will a normal "set startup" do the trick?

Thanks for any help.
