I have had issues with truncated files after a crash but this one is different. I was hired to do some surveillance work for the local PD and this entailed a simple hover for 20 min while capturing video. At 16 min I had to land and change batteries. I landed stopped video swapped out the battery and resumed. I find the first video was corrupted and split into two parts, the first 2gb is just fine the second 1gb is unreadable. This has happened two days in a row and both spit the file at 2gb with only the first part readable.
