no, I have never mounted it on universe, i'm just trying as media/usb in flash with my image.
I've a pen drive mounted as media/hdd
Sometimes I connect a maxtor hd, and that work and mount correct at restart.
Other times I use the wd disk, also with just the pen drive connected or also without, but the wd won't mount after restart.
I also tried to modify the bootmisch file as sayed in other thread but no luck.
For now I connect the wd disk after the start of the receiver, It detect the files inside of it and mount it in a provvisorial folder ( with automount I think), from this folder I can access file with dream explorer or mediaplayer. That's enought for me
