Permission problem on vfat files

Long story short:

- Using Linux root user, I dumped contents of the Windows 98 partition to
another PC via scp.
- I formated Windows and Linux partitions, re-installing all from scratch.
- As root in the newly installed Linux, I copy contents of the old Windows 98
partition back to newly installed vfat partition.
- I put line "/dev/hda1 /mnt/win98 vfat auto,umask=0 0 0" in the
/etc/fstab file.
- I issued "mount -a"
- Now, I cannot write the vfat partition, even as root.

For example, the command "chown -R 766 /mnt/win98" as root yeilds errors:

chmod: changing permissions of `/mnt/win98/config.sys' (requested: 0766,
actual: 0755): Operation not permitted

Do I need to issue a different command to have the fstab take?

Do I need to change the permissions on the "backup" box before I use scp to
bring them over? I used the -rp options on the scp command.
