,,,what exactly do you mean with "...not able to get in HD drives..."? You need to add each of your media sourches (those can be on USB-Drives, internal HD´s, NAS-Drives, etc.) to your Kodi/ZDMC Library, then you import your media. After that you can start Playback from Kodi/ZDMC.
I know the way to connect USB drivers to Kodi, but it doesn't get in the directory. It gets in using SMB connection but not with USB connection. I think that's because Zidoo is not rooted, so it can't accept other video players
