I have a problem.
Today I was copying video files from the SD card and I noticed that some of them can not be read. From 30/03 to 8/04 they are good, and then suddenly until 18/04 all are damaged.
Message from computer: QuickTime Player can not open "2019_0418_171036_105F.MP4".
The file has a name, the right size but I can not open it.
I have SanDisk Ultra 128GB card.
