I have a Synology DS416slim NAS and an external HD hooked up to it’s USB port (USB 3.0). When I try to play files from a folder on the external HD hooked up to the NAS, it’s a constant game of pushing the play button, the file playing half a second and then quitting. Sometimes I can catch the video and pause it (and I see the buffering bar fill up a little) and then play it again and it works. But sometimes I have file that will just refuse to play. These aren’t big files either. Maybe 1gig or 4gigs.
I’ve had this HD hooked up to the NAS for a long time and this has only started happening in the last few months. Previously it’d worked smoothly with any file I was playing from the external drive.
I’m not sure how to diagnose this and would appreciate some help.
