All great answers. My EHDD is a few years old so it will probably fail sometime. I'm just looking for a way to back it up as I hold all of the movies on it. I only have one receiver.
I don't know how to do the RAID. This may be of general interest. Any chance you can do a tutorial on how to set this up?
I believe
this is the drive enclosure I used, with two identical 3.5" SATA 1TB WD Blacks. Do not use greens in a RAID array. The enclosure talks to the ViPs via USB, of course.
Yes, a bit pricey. But I've gotten years of use out of it. Just follow the directions to set up RAID 1, and the following:
-set the DIP switches with the unit off and no drives installed. I think it was two up and two down, but the instructions, at least on this point, are clear.
-turn it on and hold down the reset button for 10 seconds.
-turn it off and install your drives.
Each model of RAID enclosure will have it's own way of being set up, of course. The above is for the specific model I linked.
The ViP just sees one drive, and the enclosure ensures both are formatted.
I had tried a different enclosure before, but it simply didn't work and I had to return it. It seems there are some cheap RAID enclosures that do not work with DVRs.
