Old thread but i have to say i encountered a similar problem with a friends dm800 sim 2.01 which i had the unfortunate burden of fixing for him... open pli would not initialize the hdd so i ended up flashing an 82# bootloader image to the box which done the trick...when i flashed an 84b image back it was fine also after a hdd initialize via the remote(standard image format)... i could have tried telnet commands to bring the hdd back to life but in the end i found it easier to do do what i ended up doing!!!
