I have one of the first 622's and up till now it has served me well. Yesterday it froze with a picture on the scren. Did a hard reboot and about 2 houres later it froze again. Did another hard reboot and when it was aquiring sats a notice appeared that the HDD failed. It said that you could continue to watch tv and had a continue button. Pressed the continue button and the HDD message poped up again. ( I dont see how you can watch tv with a bad HDD.) Pulled the plug for about 1 hour rebooted and everything NOW is working fine. My question is Has anyone had a HDD failure notice that never recured again.
