Yeah, the 2TB Passport is synced with the BDP-1 and the hibernation feature is still working fine.
The NAS and hard drive does become active and spin up a few times throughout the day and then goes to sleep. My next plan was to put a small SSD inside the DS119J for added silence and continue with the music on the My Passport since they are barely audible in a silent room, but it looks like that's not possible. Not a big deal at all. Playback from NAS is great and without any performance issues. It does sound a bit different than playback from the USB portable drive plugged into the BDP-1. It took a bit getting used to. I can go louder with the NAS and was turning it up more throughout. Initially, it felt as if the weight and immediacy of the music had gone down. But that just might be because it doesn't stress on transients. As I'm getting used it, I'm liking it more and more each day. It's easier on the ears.
