I have a SanDisk 256GB extreme pro SD card for my camera. It works perfectly fine with the camera and with windows, but when I instert it into the card reader on linux (fedora 38) I can't copy any files from it:

cp: Fehler beim Lesen von '.../DCIM/112_FUJI/DSCF2001.RAF': Eingabe-/Ausgabefehler

Loosely translated:

cp: error while reading from '.../DCIM//112_FUJI/DSCF2001.RAF': input/output error

the card is automatically mounted and shows up in the file explorer.

The fdisk command return this:

Festplatte /dev/sdg1: 238,27 GiB, 255835766784 Bytes, 499679232 Sektoren

I tried following this: https://www.reddit.com/r/raspberry_pi/comments/habv0q/fixing_linux_sd_card_reader_issues_inputoutput/
but it didn't change anything

Does anyone have any idea?

EDIT:
I used the wrong fdisk command. I used /dev/sdg1 as opposed to /dev/sdg which is the actual drive. Here is the output of fdisk -l /dev/sdg:

@BentiGorlich
It's a bit weird, it looks like the output of fdisk -l /dev/sdg indicates that your SD card is formatted with an HPFS/NTFS/exFAT file system, which is not the typical format for camera SD cards. Camera SD cards are usually formatted as FAT32 or exFAT.
I recommend that you backup everything on that sd card and reformat it to exfat or fat32 yourself on a linux system.

@BentiGorlich please post the output of the following command:

@BentiGorlich
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

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
