When I try to edit, create and delete a file on ubuntu I get an Input/Output error. But when I try it on Windows it works. So I think it is a driver problem, but I don't know how to fix it. Formatting also gives Input/Output errors.

When I run lspci I think this is my cardreader:

01:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. RTS5209 PCI Express Card Reader (rev 01)

Does anyone know how to fix this?

Found a working solution for my Realtek Card reader RTS5209 on a sony vaio SVE15, ubuntu 16.04 LTS.

1) Install the driver found on github at https://github.com/chrisnew/rts_pstor (official Realtek driver won't compile on Ubuntu 16.04), following the instructions contained in the README.md. Maybe you will have to install some additional components (ex. git and/or dkms), cf. detailed instructions linked below.

2) blacklist previous driver (rts_pci)

3) reboot

Detailed instructions at Realtek Card Reader not working (first answer). Be careful, there is a typo in the command 

dkms install rts_pstor/1.11
that was 
dkms install rts_pstor-1.11
for me.

I hope this will solve your problem.
