I have for a while the problem that an external hard drive (Seagate Backup Plus Slim) re-connects from time to time. While playing a film suddenly a message pops up that an external drive was connected and I am back in the main window of HT. HT does not remember where to continue. I have this problem only with this one drive and not always. Sometimes it works for weeks and then I get that message every 5 minutes. It seems to be not film related. I tried all USB ports. No difference. I don't have any problems on a windows PC. Checked the disc (extended scan), SMART, etc. Also Seatools say that the disc is fine. I have the original USB cable permanently attached to the drive. And I am not sure whether I tested also another cable. I guess that I did - but I am not 100% sure. So I guess that for some reason the X9S does not like this specific disc. Any idea what could be the reason? Had anyone of you already similar problems?
