Volumio on ODROID HC1/2 ... how to mount and access HD


installed Volumio on a ODROID HC2 using a USB Sound-Card, playback works! The Content of of the hard disk is in the local music library, but … one have to fill up the the hard disk with fresh meat

But how can I

a) mount the local disk to access / reread the media files
b) remotely access the drive to fill it up

Is it a plan, to combine a Nas like Openmediavault with Volumio?

No Feedback? Or no chance to do so?

tried the odroid thread in the community portings section?
