I recently ordered two 64GB exfat-formatted SD cards (SanDisk Extreme PRO) to use with my DSLR camera. Neither would read, and I found this lovely post that explained that I needed to install exfat libraries (https://itsfoss.com/mount-exfat/).
Unfortunately, I’m still having no luck. The cards are not recognised. The Device Notifier does not activate, fdisk -l does not list them. The only indication I have that the OS has noticed them at all is when I run dmesg, and see the following:
[16413.597058] mmc0: error -110 whilst initialising SD card
I can’t find anything on “error -110” in my google searches.
The card works well on my camera, It works just fine on both W10 systems that I’ve tried.
It just doesn’t work on my Lenovo P50’s built-in SD card reader. I’m running Kubunty 18.10, up-to-date.
I’d be most grateful for any recommendations/advice!
