Unable to mount the INTERNAL SD Card

[dgdimick]

 formatted exfat, 

Linux can't handle exfat without installing the exfat library...

Thanks for the reply, 

I should have been clearer, I have installed the exfat libs. I assumed by stating that I can mount the SD card using a USB adapter and a OTG cable would have been inferred this - my bad for being unclear.

I do thank you for making sure I'd installed the libs, since this could be a core issue.

Any other ideas?

I've tried with a few SD Cards now, both 512 Gig formatted exfat, and tge cards are not showing up on boot, "dmesg" and "lsblk" are not showing them as well.

I'm running Phosh, is it an issue with Phosh?

I'm able to mount the SD Card via an OTG cable, as well as a Windows computer

Thanks

what do you see when you run this directly after inserting card:

sudo dmesg | tail -20

?

Thanks for the reply.

Since the SD Card is installed in the Slot INSIDE the phone, I'm not sure what your asking. I've run dmesg a number of times trying to find any "/dev" entries.

When I use the OTG and an SD Card to USB adapter it comes up as /dev/sda1 and allows me to mount it, R/W.
