If you are having any read issues, you may want to look at using 
'ddrescue'. This will make an image of the partition you can either 
mount or 'dd' to another HD.

There is also 'Mondo' this will make CD or DVD images for you. Not sure 
if this in included with Knoppix.

For future reference there is backuppc to maintain backups over a 
network or for doing backups from your desktop to another partition or 
networked system there is Kdar (the KDE disk archiving) tool.
