Check for Errors: Run a file system check on the exFAT partition to identify and repair any potential filesystem errors.

$ fsck.exfat -y /dev/sdg1

Try mounting the SDcard with different mount options. Create a directory where you want to mount the card, and then use the mount command with specific options. For example:

$ sudo mount -t exfat -o ro,umask=000 /dev/sdg1 /mnt/sdcard

This mounts the SD card as read-only (ro) with a more permissive umask. Adjust the options as needed
