Dear ,
Thanks for your respond. i just purchase the receiver from Germany so i am expecting it is original. the device manager was part of the folders i saw it while i am checking the list of folders.

Hi All,
I do have DM 800 PVR. i tried to install internal HDD the main problem i can see the HDD in the device manager but i could not see it in the system setup in order to mounted. if anyone has idea about how to fix it please let me know.
Also if i try to record, it give me size is less than 100MB which is wrong actually 500GB
