Access Privileges

I just purchased a new notebook with the Windows Vista OS.

I have installed the iTunes software for my iPOD.

When I try to sync my iPOD, it will sync my music files but does not sync my
photo files.

I get an error message: "Cannot sync iPOD. You do not have enough access
priveleges to perform this operation"

I store my photos on an external hard drive linked to the notebook through a
USB 2.0 port. I have tried to change the ownership of the individual folders
as well as for the entire harddrive itself. I am the administrator on this
computer.

Where do I go from here?
