broken sd card reader?

[kratti]

Any idea what I could try to do when any sd card that I try on my pinebook pro gives I/O error when I try to write to it? I've so far tried 3 cards, the first of which I used earlier to try several distros on the pinebook pro and it always functioned flawlessly and was really fast. After I got the I/O error on that sd card I purchased two new sd cards but both of them give an I/O error straight away when I try to write on them on the pinebook pro.

Unfortunately I don't have any other sd card readers with which to try if the cards can be used and I really don't want to buy unneccessary hardware just for troubleshooting. Is there anything I could try with just the pinebook pro?
