copy

I am running 12.04 live from cd and trying to copy some important files from a mounted hard disk to an external disk. (My previous installation of 10.04 crashed and I want to install 12.04, and back up some data before that).

When I try to copy files from the mounted disk to the external one, I get the following error:

There was an error copying the file into /media/New Volume/L300_Bkp_2012_06_04/pics
Error opening file: Permission denied

Is this related to the source(mounted hard disk) or the target (external disk)?

How do I get around this?
