Hello Tez,

The command 'ls -ld /media/rio' gives me the result:
drwx------ 3 user user 6144 1969-12-31 19:00 /media/rio

I don't quiet understand the permissions for the file but I tried 
to change the permission by typing the command:
user at ss-xubuntu:~$ chmod og=rw /media/rio/

But it did not work.  The result I got was:
chmod: changing permissions of `/media/rio/': Read-only file system

Nevertheless, I tried to open Krusader and copy a music file from 
my music folder to /media/rio and it did not work.  I got the 
message I had gotten before:
'Could not write to /media/rio/Heaven.mp3'

Not sure what is going on.  Thanks for helping me figure this out.
