Continuing the discussion from My book live never sleeps:
I know the topic above is fairly old, but I noticed a number of DirecTV references in the thread that were looking for some follow up information.
I’ve had a pair of 3TB MBL drives on my network for a couple of years. They have always worked great and gone to sleep when expected (10 minutes or so normally, hours to days later if I just uploaded large amounts of video/picture data). About two weeks ago I changed from Uverse TV to DirecTV (with Genie DVR, I think it is the HR44). Since that upgrade, neither MBL went to sleep again.
So it was pretty obvious that the DirecTV box was accessing the drives, but I don’t know why. Other posts referred to turning off the media server on the DirecTV box, but I didn’t find anything about that on the box. Instead, I turned off Twonky and iTunes on the MBL and it worked. The drive is back to sleeping exactly as expected. I already had remote access turned off, so I’m not sure if that is required as well.
I realize that if you need those features then this doesn’t really help, but hopefully it is useful to someone. If you need those features then a solution would need to be found to stop the DirecTV box from accessing the drives regularly, because that is the issue, not the MBL. I poked around a bit on the DirecTV box, but didn’t find anything that looked like it might allow me to prevent those accesses.
