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.
just in case, you tried on two computers, but is it the same card reader ? I’ve seen more dead microSD to usb/sd readers than sd cards in my life
Just for clarification, were you able to read the card from this machine before?
I had a similar issue where my SD card reader was not able to read a card with a newer standard like SDXC or whatever it was and i had to find a newer reader.
If you just want to try to recover, PhotoRec This does require it to at least be able to power and have a raw device to look at, though it doesn’t have to be able to be mounted. More than just photos can be recovered.
Had pretty close to the same results with PhotoRec vs commercial tools on windows.
If you need the data, a solid state recovery specialist may be able to assist you. Surely won’t be cheap as it generally requires reading directly from the flash through soldered wires or jigs.
