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?

This is mostly related to the mounted hard disk. You can try these to workaround the problem.
Using root power.
Press
Alt+F2
to bring dash command prompt. In that window, typegksudo nautilus
. This will open nautilus with root permission. Then you can copy the files safely. Remember to close the root powered nautilus after the work finished, also do only what you wanted to copy.Take ownership of the mounted file system
If the above method does not work, You can use this.
Open a terminal, and type
sudo chown user:user /media/New\ Volume
to take ownership of the file system. Then copy the files and reboot. Please note, it is only recommended, if the above method does not work.Hope this will solve the problem
