How do you mount a drive (internal or external) in READ/WRITE mode using the Ubuntu 12.04 Live CD / USB?

I can boot the computer with the LiveUSB but Ubuntu is only mounting the drives as read only ...


You can remount in read-write mode by running:

sudo mount -o remount,rw <filesystem>


The hard drive is mounted as read/write from the ubuntu live cd/usb. The disk is mounted when you click on the drive icon on the GUI, or issue a mount command in the terminal. The only thing is that you have to use sudo to issue command to write to the disk.

For an example, the disks are mounted to /media/ubuntu/disk1 and /media/ubuntu/disk2 You want to copy some files from disk2 to disk1, then run following command (with sudo)

sudo touch /media/ubuntu/disk2/file.txt 
sudo cp /media/ubuntu/disk2/file.txt /media/ubuntu/disk1/file.txt 

It works as well in ubuntu 14.04 and 16.04
