Tez,

Thank you for the quick response.  But following the instructions did
not quiet work out for me.  I did not have any problems mounting the rio
using the 'pmount' command.  But when I tried to copy a file from my
hard disk to my rio, using Krusader, I got the message 'Could not write
to /media/rio/Heaven.wma.  What gives?

Thanks. Funkid
