I am a little unclear on your fix, "chmod -R" specifically. You shouldn't
have to set permissions recursively or to the drive itself.

Assuming you are the same user who has been mounting it all along and

assuming the drive is sda1:

 # pmount /dev/sda1

That should get you a directory with the name of the label of the drive or,
if no label, "sda1," with permissions set correctly in /media .


Then you can link it for convenience of location and and name if you like.

 $ ln -s /media/label_name_or_sda1 /home/user/new_name

If you are in Gnome or KDE, I believe nautilus or Konqueror should be
mounting it automatically.
