NAS adapter for existing hard disk



Does anyone have any experience of a device like this one

I have a nice new external hard disk that i would like to use as a NAS hard disk. This product seems to do exactly what i'm hoping for.

I persume if the HDR is allowed to become a Network Server with future firmware upgrade i wouldn't need to buy a NAS adapter or NAS hard disk as i could plug my existing non-NAS Hard Drive into the back of my HDR?

Will the HDR-FOX T2 work with the Samba server on this device ?
This Addonics NASU2 does not work with the HDR-FOXT2.
Bought one and tried it have to ebay it now.
Does anyone know of an NAS adapter that does work with it.
