How to block devices with removable storage in users Citrix session using Citrix Policy

Hello there,
I need to block access to  devices with removable storage in users Citrix session using Citrix Policy. I created policy and set-up the following setting in CItrix Policy I created, but still the Floppy drive and DVD Drive appears when I log into Citrix session. Screenshot
The Citirx XenApp 4.5 server on W2K3 OS.

Please advise as to what steps I need to follow? to block the acess.

Thanks and Regards
