Wireless NAS or HDD?

Hi,
I’m not experienced but I was thinking about making my WD-2TB desktop HDD accessible via WiFi.
Is it possible to use imp as a wireless intermediate for my external HDD?
There is no need to access it via internet and just suing it as a shared media at home will be sufficient.
Data types are documents, video and audio.

No, the imp doesn’t work for that sort of thing. You’d need something like this:

…or a wifi router with a USB port.
