Maybe with the WD drive accessory?
You can use the My Cloud app to access the My Net N900 drive remotely.

Please confirm that this is only N900 Central. I only wasted 3 days of my life due to early paperwork not stating that. I think the new documents state support is only N900 central models with built in hdd. I do not think external USB hdd will work. WD please confirm. The reason I purchased the N900 non central was due to lan ports and this feature, only to be bamboozled.
