Sometimes when I continuously use the USB port (like watching a movie from a HDD) it suddenly shuts down, along with the onboard bluetooth and wifi (adapters just disappear from device manager). After some time they come back up but BT keyboard/mouse and wifi won't connect anymore until I reboot the tablet. Has anyone encountered this problem ? Is there a fix or a way to prevent it ? It is a crap HDD though, with lots of bad sectors I've fixed through some software before, can this cause the problem ?
