Toshiba Canvio aerocast just bought one it doesn't do what I thought it would do!

 

Thought it was wireless would just connect to my smart TV etc as it is, but I think I need a Toshiba Canvio Wireless Adapter for External Hard Drives as well, plugged into usb on TV and PS3 not recognized as is.

 

Trying to figure how to connect to chromecast has anyone had any experience with this device?
