Exxpanding Yun Disk Storage

Hi,

I am trying to expand my Yun Disk Storage using a SD card. But every time I try I get this error 'Disk Utility needs at least 1MB of flash memory'. Resetting board to factory settings and flashing a new OS doesn't work.

P.S., After flashing a new OS I could see just around 700 KB free space in my root.

Expand the storage by SD card/USB flash/USB hard drive for Yun & compatible
