I assumed the key file was compromised  as I sent it along with the mail. I am 
a little disappointed about my passphrase as I have committed it to memory and 
haven't used it for anything else. Oh well.

I have plans on getting another hard drive this afternoon and starting the 
cloning process. 8TB drive, so going to take a while. After that I was going 
to get back into your procedure. I will probably need some more hand holding, 
so I will post back when all that is done.

Thanks.
