I will do that. I didn't think my mac would recognize the extended HD without booting into it. Here goes... Uh oh. Got this message in Terminal: [b]Last login: Thu Apr 23 11:33:24 on console
MacBook-Pro:~ myname$ sudo dd if=/dev/rdisk1 of=/dev/null conv=noerror bs=5120
Password:
dd: /dev/rdisk1: No such file or directory

[/b]

Update: Oops, I forgot to connect my ext. hd. I did connect it and tried Terminal again but it wouldn't let me erase the first message. How to I clear it? I quit Terminal but it's still there. Why is this so hard?

That's correct.
