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:

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:

        I’ll have to look into it. I think my fstab is still referencing ntfs-3g.

        Found this:

        Note: All officially supported kernels with versions 5.15 or newer are built with CONFIG_NTFS3_FS=m and thus support it. Before 5.15, NTFS read and write support is provided by the NTFS-3G FUSE file system. Or you can use backported NTFS3 via ntfs3-dkmsAUR. Paragon Software, the author of the kernel module, has not yet released userspace utilities for NTFS3. You can use NTFS-3G userspace utilities without NTFS-3G driver via ntfsprogs-ntfs3AUR.

          Interesting. I’ve never had any major issues but I don’t deal with NTFS all that often so maybe I’m just out of touch.

          What would be cool is if the windows btrfs implementation matured enough to be stable.

    Which partition is the one automatically mounted? That sdcard seems weird, it has 4 partitions occupying the same space. Also I would try to mount all 4 partitions manually and check if one of them works.

      The partitions also start at a very high sector and are larger than the SD card is supposed to be. I wouldn’t trust the information in that table.

        Yeah, the partition table is messed up. Format the card from Linux. It would probably work from Windows too. But the camera is doing something wrong.

          From another comment chain it looks like they used fdisk -l /dev/sdg1 instead of fdisk -l /dev/sdg

        Not sure, but one of the commands there showed /dev/sdg1p1 which is a weird name used for subvolumes if I remember correctly.

          there is no such package. And I mean it mounts fine. I can search all the files, just copying them or writing to the card doesn’t work

        I don’t know, the camera formatted them, but I highly doubt that it is NTFS. So propably exFAT…

        If you have the filesystem mounted, I believe you can see in /proc/mounts.

    The partition type column is a bit strange with SpeedStor. I only found this information on that

    61 SpeedStor

    Storage Dimensions SpeedStor Volume. This is a Non-Standard DOS Volume. (Disk Manager type utility software)

    It is also strange that all four partitions seem to occupy the same space and have the same size which is also significantly larger than the 256GB you mention.

    You might not get an I/O error for the partition table but I don’t think it is reading an actual partition table describing the SD card.

    Have you tried formatting a different SD card in your camera and seeing if it has the same issues? This would help rule out an issue with the card itself.

      I have, but I didn’t look at that one yet. It is even more strange. It doesn’t recognize even one partition on it… (I also know that this one works, I imported files from it yesterday on my windows laptop and it worked perfectly fine, no files are corrupted

    Is your Linux laptop dual-booting Windows? I am wondering if you are using the same SD-Card reader to read the card on both Windows and Linux?

    This is relevant because if your Linux laptop is different it could be a problem with the SD-Card reader on your Linux machine.

    Assuming your card reader works fine on Windows but not Linux, it is probably a driver issue. Linux is clearly reading the SD-Card boot sector since it is reporting information about the partitions. But if it is a hardware issue (not likely if it is working on Windows with the same card reader), it may start to read the card and then fail as soon as it starts to draw too much power or heat the card up or something.

      yes I am, because the files I copied from my the sd card to my windows machine are fine. I can import and edit them in darktable without any problems

    I was having this problem in Mint until I rebooted the laptop with the microsd inserted.

        @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

    @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.

      I just reformatted it on my linux machine. So I choose exFAT again, because thats what it was before, that’s what I know the camera can handle and I have the exact same problem… I think I just surrender and import my photos on my laptop all the time…

      The partition type after a format is btw still NTFS/exFAT/HPFS. So that is just a compatibility thing for it to work on basically all systems I think…
