I cloned 11.10 from 8 GB to 16 GB USB flash drive
Wow! Ubuntu is great!
Using Plop, I booted my 11.10 installed on a Sandisk 8 GB USB flash drive.
I plugged a 16 GB Sandisk USB flash drive into a powered USB hub.
Using Applications/Accessories/Disk Utility I double checked that my system source 8GB USB flash drive was /dev/sdb and my target 16 GB USB flash drive was /dev/sdd.
Simple, clear, straight forward.
dd if=/dev/sdb of=/dev/sdd
It took awhile but every bit in /dev/sdb was copied to /dev/sdd
What really surprised me is that Ubuntu 11.10 allowed me to copy from a running system to a blank USB flash drive.
My first thought was that I needed a Live CD to copy from a flash drive not being used for the system.
I am now running on the cloned drive.
I am SOLD on Ubuntu!
