So after booting to the CentOS 5.3 LiveCD, I can get to '/mnt/ 
VolGroup00-LogVol00'

doing a: 'sudo du -h --summarize /mnt/VolGroup00-LogVol00' I get: 28GB  
used.

So can I 'rsync -av /mnt/VolGroup00-LogVol00/. /mnt/disc/sda1/.'
(sda1 is the 500GB USB Drive that I am wanting to put the data on.)

Best,
