There are some useful terminal commands such as:
For more info type man chown or man chmod
But the basic usage for chmod is
chown username /place/or/file
This is how I regain ownership of a filesystem.
Of course you may run it and it doesn't work... You may have to run it
as sudo and you may need to use -R to recursively own all files in a
directory as in
chown -R myusername /the/path/to/the/drive
(ex chown -R farinet /dev/sda7)
