I have 12.04. New to the command line. I have an external hard drive that works on one of my computers, but I'd like to use it with another. When I try to put files onto it, it tells me that it's read only.
But there must be something I can do about that. I browsed through other similar questions and tried to go through Nautilus to change the permissions. I get this
Sorry, could not change the permissions of "One touch": Error setting permissions: Read-only file system.
