We are seeing ocasionall sd card corruption on some units deployed in the field.
The hardware is EM module and the sd card is a mini sd card Verbatim 2GB.
The corruption manifests as a lot of files and folders with random names (letters and numbers) being created out of the blue.
When you load the sd card in a windows PC and try to open the files is doesn’t. If you try to delete a folder or file, they won’t get deleted.
The only solution is to format the sd card again.
Is there anything that we can do to add robustness in the app as far as the sd card r/w is concerned?
I believe we are doing everything as supposed: mount, dismount, closing files, etc.
Last week on a particular unit the garbage files and folders look like pieces of code.
As I couldn’t copy the file structure I did a print screen which I’m attaching.
Maybe you guys can make sense out of it.
