Got my 750 GB external Seagate HD replaced. This time I mounted it in a cooler location with a direct SATA connection to avoid overheating. I think the Nexstar 3 enclosure is fine for smaller / low-power disks, but don't want to take the chance of burning another one up in that enclosure. Since the enclosure only provides power and a direct eSATA connection anyway, I found another solution to do that with better cooling.
I still feel that this is not the best choice for a disk for this type of add-on to storage for the Pace CableCARD HD boxes, but right now do not have the change to try out other drives, like the Hitachi CinemaStar low-power streaming-optimized ones that I think would be a better choice. In any case, it would be nice to have the option of migrating files directly from one drive to another for purposes of being able to change out the disks without losing content. Lindend, can this be a feature request for a future firmware update?
Finally, it seems that the disk is very frequently written to, at least with some series recordings programmed in. With a plain-vanilla SATA drive like this, I hear the heads move all the time, and it is pretty annoying. It would be better if this were controllable, or if the Pace boxes had some sort of buffer to cut down on this type of head movement, as it can't be good for the drive at all (optimized or not). What options can we or you pursue to reduce head movement due to TV Guide updating, series recording checking, etc.? This noise happens even when no other activity like recording or playback is happening on the Pace box.
Thanks for your attention.
