    The FAT32 file system on your removable drive does not support permissions
    or owner/group security. (You may not have noticed, but it doesn't support
    symlinks either.)

    In order to transfer files maintaining the metadata, you have two options:
    - Reformat the drive to use UFS(FFS) or Ext2/3. This will involve less
    work in the long term, but will make copying files to a Windows machine
    impossible.
    - Archive the files you want to transfer in a .tar.gz file (tar cvzf *)
    and copy the resulting file to the drive. This will allow you to maintain
    permissions and symlinks, but will require more work every time you want
    to transfer files.

    Hope that helps!
