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:

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