Hi,

I received System 7.0 several days ago but am hesitant to test it
on my current hard drive because I am not sure whether it is worth
installing it despite its reviews.  I have an internal HD, as well
as an external HD which I use mainly as a backup.  I was wondering
if I can install System 7.0 onto my external HD rather than the 
internal HD.  Is there anyway to "deactivate" the internal HD so
that only the external HD boots up?  I know that it's not 
recommended to boot two systems at the same time.  Can anyone
help?  Thanks in advance!

Phillip
