I've just tried to create a folder on the external h/d which failed.
This is the error report;-
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
mkdir /media/8eef3b99-c17b-4913-ae61-d34c7fd5d459/test
mkdir: cannot create directory
`/media/8eef3b99-c17b-4913-ae61-d34c7fd5d459/test': Permission denied
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Any ideas for a solution please?
Sharon.
