Hi hva,

I'm going to change the default to not show VFAT/NTFS drives, so that
the only visible hard disk partitions will be those in /media, which you
probably want. :)

Anyway, this particular policy is in
/usr/share/hal/fdi/policy/10osvendor/20-storage-methods.fdi:

      <!-- Here follow volumes we specifically want to ignore - it is the -->
      <!-- responsibility of software higher in the stack (e.g. gnome-vfs) -->
      <!-- amd mount programs (e.g. Mount() on HAL) to respect volume.ignore -->
      <merge key="volume.ignore" type="bool">false</merge>
      <match key="@block.storage_device:storage.hotpluggable" bool="false">
        <match key="@block.storage_device:storage.removable" bool="false">
          <merge key="volume.ignore" type="bool">true</merge>

          <match key="volume.is_mounted" bool="true">
            <!-- Show windows drives -->
            <match key="volume.fstype" string="vfat">
              <merge key="volume.ignore" type="bool">false</merge>
            </match>
            <match key="volume.fstype" string="ntfs">
              <merge key="volume.ignore" type="bool">false</merge>
            </match>

            <!-- Show /media/ and /mnt drives -->
            <match key="volume.mount_point" compare_gt="/media">
              <match key="volume.mount_point" compare_lt="/media0">
                <merge key="volume.ignore" type="bool">false</merge>
              </match>
            </match>
            <match key="volume.mount_point" compare_gt="/mnt">
              <match key="volume.mount_point" compare_lt="/mnt0">
                <merge key="volume.ignore" type="bool">false</merge>
              </match>
            </match>
          </match>

The volume.ignore property is the key bit here; it defaults to false for
hard disks, and needs to be set to true for the subset of partitions
which should be shown
