Hello everybody,

I’m trying to read a (probably damaged) microSD card from my computer (tried with two different computers, both Arch Linux, which can read other card without any problems). There isn’t any singal of life (no /dev/sdX, nothing with GParted, testdisk, …); the only thing that I found was in dmesg. Here’s the output of sudo dmesg | rg "mmc0":

Any idea on how to resolve?

    Try putting it in the freezer for a few minutes before trying to read the data. Or heat it up slightly.

    This is an old trick I’ve used to recover data from a hard drive or two. I suppose it could help if the problem with the SD is some kind of microscopic fractures.

    It should be emphasized that this is just a temporary workaround at best.
