I added the usb stick to check if it was only networked drives that were giving problems.
It appears that once this box fails to read that it is incapable of correcting the hangup, something that the firmware should be able to account for and reset itself.
I found that my NAS drive goes to sleep after 45mins of non use, thinking that the WD couldn’t wake the drive, I turned the sleep function off.
This morning I moved the Lan cables so that the NAS was connected into the BT HUB5, instead of the Gigabit switch box.
I pulled the power plug on the WD box and restarted it.
Reads and plays memstick and NAS.
left WD box on
Tried about an hour later, still plays both.
left WD box on
Tried after another hour, reads the NAS directory, but fails to play and video.
NAS was left running all the time.
I’m at a loss what to try next.
So did playing video files from the flash drive ever quit working? That is clearly important, as if this is happening only with the NAS, then that points to a problem with the SMP communicating with your NAS.
What I read on the forum definitely suggests that the SMP is not terribly robust about recovering from communication failures. There also are a fair number of people that have gotten on the forum and reported issues that are ultimately traced back to their NAS devices. Definitely has made me leery of buying an NAS, when a $300 PC with Linux is vastly more powerful, flexible, and (apparently) dependable.
A couple other things I am not clear on:
(1) How are you accessing files from the NAS? Windows Shares (SMB), NFS, a media server?
(2) If SMB/NFS, are you using the Media Library?
(3) Your networking from the SMP to the NAS is completely wired? (No Wifi links?)
(4) When you say your SMP still “reads the NAS directory” but cannot play files, what exactly are you doing that makes you think it is still reading the directory at that momemt. (I ask because it is likely that some information has been cached.)
Can you wire both the SMP and the NAS to the switch, to eliminate other networking device issues? (Then connect the switch to your router to maintain Internet connection.)
Do you have a PC that you could enable a share on, move a few video files to it, and see whether the same thing happens with it? This would help test if there is something about the NAS that is causing problems.
