Dataflash logs not recorded correctly

After dozens of flights and some crashes today my dataflash logs were not recorded anymore.

While the numbering of today logs was fine the date of first two of logs went to 01-01-2000 . These two logs were made at home and the last one to 01-01-1980 , was done at the airfied

The last log has 0 bytes length .

In fact at the airfield I have disconnect the battery or reboot the Pixhawk at least 5 times but no logs were recorded.
The Micro SD card was installed in the Pixhawk slot correctly.
