If it is the same as the 6xx series you can backup your configuration. Hidden channels. Guide preferences etc and transfer that to another reciever.
I had to reformat my hard drive and its contents when I hooked it up to the 830 from the 630. Nothing was saved, the rest can you transfer guide preferences etc, my guess would be no, I could not find a way to do it.
The 830 is basic , or so it seems as far as bells and whistles, It has no record light on the screen(front panel), no sat light on the front panel either. Just the power button light. No clock etc. It seems to work good as far as reception, recordings work good, no audio issues, channel change quick, Guide functions work good.
The USB2.0 standard provides up to 0.5A from the port. I tested an external 2.5" drive rated at 0.5A on the 630 once and it worked, even though it's not recommended. I didn't use it for long since it was just a test. My long term solution was to put a 1TB drive in the 630. The 830 already has that.
Will the USB power a 2.5" drive?
The official answer is no, you need a USB3.0 port for that. That, of course, begs the question of why the 830 lacks a USB3.0 port. The other solution is to use a Y cable that uses 2 USB ports to power the drive. Some 2.5" USB 2.0 external drives come with a suitable Y cable and they can be purchased on eBay. Then the issue of the 630 and 830 only having one USB 2.0 port arises. If the 2.5" USB drive has a power connector, a 5V power brick can be used to power it.
I am starting to understand why Shaw doesnt seem too excited about the product.
So far theres nothing thats telling me that its better than the 630 except for the bigger HDD but its not that difficult to replace the drive in the 630 either so even there theres no advantage...
I am super disappointed... I guess I will just buy the remote for my 630 and keep using it...
