So i bought the Tesla recommended SanDisk Ultra Fit 128GB USB 3.1 flash. Today after a week of driving I got a message that a video file could not be written because the transfer speed of the usb is too slow. (nonsense). So I plugged the USB into my computer to see what was there and in the TeslaCam folder there were 3 sub folders. The one called recent clips had 3 videos, two of which were corrupted. The next folder called Saved Clips had 3 days worth of sub folders labeled with the date and those were all full of videos of just pulling in and out of the garage! The last folder labeled sentry mode actually had sentry video from various stops I made and turned on sentry mode so it appears to be working. Any ideas why I got that message today about cant write or why some videos were corrupted files? Also I expected the recent clips to have dash cam video of me driving around town but it only has me going in and out of the garage?
