someone sent this link a while back, this is system of MRZ09 will all volume, rw, setup and system, so maybe replace prg0 and prg1 with mrz07 then maybe work?
if you still have the the all hdd files on your computer, could you please upload it on MEGA.NZ, because i have hrz08 and hdd is corrupted so hrz09 data should work. try to upload LDATA on mega please.
