Im using a very good image, openatv 4.2 for my dm800hd, very stable and reliable. I just can't get the hard drive formatted and Ive done this dozens of times before with other boxes.
I usually just format the drive to ext4 on my pc using mini partition tool but have also formatted to fat32 and tried rebooting then initialising. also tried going into device manager and setting up the mount but it will not mount to media/hdd and it crashes the box with green screen...
