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:

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/sdg1instead offdisk -l /dev/sdgThats right, I posted the correct output here somewhere, but here it is again:

lsblkonly shows that/dev/sdg1is mounted…Not sure, but one of the commands there showed
/dev/sdg1p1which is a weird name used for subvolumes if I remember correctly.
