Hi Robert, Thanks for ur help.When i login as root it does not give such error,thanks! Yet the information displayed does not match with that of df -h. df -h shows much more space used than the information retrieved by rt click.

As regards the original problem, "some contents unreadable" - that is often just a permission error. For example, if you became root and edited a file in your home directory, then only root would be able to read it. That can be solved with the "chown" command. best regards, Robert
