I have two basic Roamio boxes, both bought recently with normal 500GB drives. I changed both to 3TB. One was done months ago and one is fairly new. One runs TE3 and one TE4. I also have two Roamio boxes with 1TB and 3TB green drives. Neither new box gets much use and one (TE4) is put into Standby. When I access either Roamio with the red drives, there is a delay if they have been idle for a while (hours). I'm curious if they are shipped with power down enabled. I could just buy another one to test, but since each of the drive is about 50% full of movies, I'd like to get some feeling if it is the drive and I should I look moving the programs then running the WD diags? When it was just TE4 I blamed TE4. But with TE3 now having the same issue, I don't want to blame the software (for this anyway). Thanks.
