Can't read sdcard

cybervigilante · 08-13-2018, 01:57 PM

I can't read my SD card. I tried downloading the driver from Realtek but the makefile wouldn't make and when I finally got it to, the c program was full of errors. Is there a generic linux program that has a lot of SD drivers? I'm tired of struggling with the Realtek driver. Failing that, is there any OS I could download to put into a virtual machine that would read and write the SD card? I mainly need it for a can-type mp3 player I keep on my bike.

I have a Dell Latitude E6410

You didn't provide any information about what distro you're using, what program you're talking about, what error messages you received, and finally why you even tried to compile it and not just used a precompiled package for your distro, so the only thing I can do is to give some hints:

The drivers for SD cards readers are actually a part of linux kernel, not of some user space program. Seems unlikely that you're using a self-configured kernel, so you distro should already include the drivers. Having done a bit of googling, the card reader in your laptop should be supported since kernel 3.1 from 2012. So you either have a very outdated distro or your SD card is corrupted.

MX Linux. sandisk micro sd. The driver downloads for linux were not precompiled - just c programs and a makefile. I know windows will run it but you need windows to install windows pe which I could put on virtual machine. Is there anywhere I can just get a bootable PE ISO?

Finally got an error at least from dmesg | tail, so I am seeing the card but no initializing it.
mmc0: error -110 whilst initialising SD card

So it's not lack of card reader driver and you don't have to compile any drivers at all. The device mmc0 is up and running. My bet you just have a dead SD card. Happens way too often with them. I had similar output with different error numbers for dead SD cards. Try to use another one to see if that one would work.

Thanks. Had a feeling it was dead. I even installed a later kernel on my backup Lubuntu machine in case it was a kernel error, but that didn't work either.
