Hi, Modifying /etc/hal/fdi/policy/preferences.fdi like following code, fixes this problem:
<!--
<device>
<match key="storage.hotpluggable" bool="true">
<match key="storage.removable" bool="true">
<merge key="storage.automount_enabled_hint"
type="bool">true</merge>
</match>
</match>
</device>
-->
restart dbus after modification.
