I posted this over on the dish dtv-pal forum, but haven't had any responses, so thought maybe I should have posted it here... as I said there, hope the amount of detail I'm giving is ok (I am a rookie...).
I have a CM7000 DVR that we've had for over 3 years and it's been great (other than the little issues we all would have loved to have seen fixed with a firmware upgrade). However, as of last week, it started constantly freezing for up to a minute when it is doing most functions - changing channel, returning to the list of recorded files after stopping playback, deleting a recording. It will freeze up, normally with a black screen, then will eventually find the picture, but just a frozen picture, then it will eventually find the channel and be fine until we change channel, etc. It's also clear that it's freezing up when it starts a second recording (eg if I'm recording something from 8-9 pm and start something at 8:30 pm), because there is a skip on the file that was already recording. While it is frozen, it still receives signal from the remote (the green light on the front flashes for each press of the remote), but nothing happens. Sometimes it will cue these signals up, sometimes it won't. Has anyone else had this issue?
It is happening with all channels and once it has found the channel, the signal strength is very high, so it's not that it's a weak signal. I also plugged the antenna cable directly into the TV and checked the TV signal with analogue pass through and it's all fine, so it's definitely the PVR. I have done a soft and hard reboot and nothing changed. We have not changed anything about our setup (eg moving the antenna, adding new components, changing cabling, etc).
I contacted CM support and they suggested doing a factory reset and re-formatting the drive - did both of those and no dice. I opened the case up using the super helpful instructions in this forum (thanks!) and while there was a bit of dust, it was nothing crazy - I still cleaned it and it didn't make any difference.
I'm assuming my next step is to replace the HDD (give me a chance to upgrade anyway) or else I'm looking at something serious like a dying tuner...? I've read through the forum as much as I can and have seen that as it says above, I should be able to get any 80Gb-1Tb drive, as long as it's 3.5" (I don't want to try the mods to do a 2.5"); 5400 RPM; SATA I or II (or III that can be jumpered down). I've looked at our local retailers and none sell any of the drives that have been noted in these forums or the ones people have mentioned throughout. So, I wondered if anyone had any luck with:
Western Digital WDBAAY0010HNC-NRSN
Western Digital WDBABC0010BNC-NRSN or
Western Digital WD10EZRX
Appreciate any help!
