I have just retrieved a couple of moths from the field and unfortunately miscalculated the space requirements so both filled their cards. One had retrievable data (about 10% of it) before the card corrupted, and the other was toast, literally. It got very hot and broke apart in the card reader.
Is there a way of having a space check in the firmware to prevent such accidents in future?
The cards were Toshiba Exceria M302 32GB Micro SD Memory Card 90 MB/s 4K - THN-M302R0320EA which had functioned perfectly up until then.
Superb. I was procrastinating another task by starting to browse the Github code. I'm sure there is plenty of scope for enhancement.
Hi, We have firmware update in a couple of weeks which will change the file name format to something more readable and should also handle write failures to the SD card more robustly. Strange that the card phyiscally broke! I imagine that the card was reporting write failures and our hardware ignored them. We did this originally so that minor glitches on writing to a card wouldn't prevent the rest of the file from writing but we now think that the better way to handle it is to just abort the file and then try again when the next recording should start.
