Did you create a 32gb partition on the SSD for TesaCam?I was updated to 2019.8.3 yesterday. Last night I upgraded from a USB Flash stick (2 partitions, one Music, other for TeslaCam) to a SanDisk 1TB USB SSD partitioned same, this was done to fix a Music stutter, which it did fix. Went on some errands today and thought I'd test Sentry mode. All recordings were working fine with no garbled images (they Were garbled with the UDB Flash drive as others have stated and shown) when Sentry mode was off. With Sentry mode ON The Front camera and Left repeater were fine but none of the Right repeater files are readable, won't even open. As soon as I got back in the car, Sentry Mode turned OFF and then the right repeater starts working again.
So, from my experience the gabled images are from slower Flash drives, since the garbled images cleared up with the SSD drive. However the Sentry Mode has a problem...
***UPDATE: All of the Right Repeater files are 0KB, nothing recorded while in Sentry Mode.***
Seems like the flash drive speed shouldn't be an issue since its faster than USB2 like the car has already?
