Recovering Files on Pocket PC

I need to recover files from my Pocket PC's internal storage which I can't remove like the additional storage cards. In windows explorer I can see my Pocket PC and explorer all file locations, however recuva will not display anything but C: drive so i can't scan the Pocket PC.

The pocket PC is an IPAQ running Windows Mobile 2003 SE and my computer is running Windows Vista Ultimate with Windows Mobile Device Centre 6.1

Any ideas would be much appreciated.

Thank you

James
