The ownership of the symlink is unimportant, the ownership of what it
points to is what affects you.

Windows had no concept of ownership (except NTFS under NT but that isn't
supported by Linux anyway)

You need to pass options to 'mount' when the partition is mounted, this
will set the permissions of the entire drive. 'man mount' and 'man fstab'
will point you in the right direction, but in the meanwhile...

Basically the partition is mounted by 'root' as the system boots so all
the entire drive is owned by root. You need to give the uid/gid/umask
options to mount in the fstab so it is writeable by mortal users.

/dev/hdd1	/mnt/win_e	vfat	uid=root,gid=users,umask=0770	0  0

this (should) mount the drive owned by root but writeable by the group
'users'

/dev/hdd1	/mnt/win_e	vfat	umask=0777	0  0

this (should) mount the drive owned by root but
readable/writeable/executable by everybody.

I don't have an MS-DOS partition to test with so I can't be sure I haven't
made a mistake but it should be enough to point you in the right
direction.
