Carbon Copy Cloner help

[Dan Farley]

Ok - I'm ready to do surgery and replace my hard drive on my 500 MHZ iBook.
In preparation, I used CCCloner to make a clone of my current 10GB hard
drive to an external firewire drive (partitioned for 10GB). When I make it
my startup drive, unlike my current setup - it wants me to login. When I do
- it doesn't seem to recognize my password. Any idea what's going on. I
don't want to proceed until I'm confident I can clone back what I remove.
Thanks
Dan
