I have one micro sd card which my laptop does not read and neither mount nor show in lsblkor blkid. Using tail -f /var/log/syslog, shows that there are problems:

The sd card (Sony micro sd, HC, 16 GB, 90 MB/s, SR 16UY3 works fine on my Android phone and in my camera, but not on my laptop (Ubuntu 18.04, Acer TravelMate 4500). Also with GParted, I cannot see the card. Other sd cards work fine on the laptop.
Information on the sd card reader (I also updated the driver to exclude that possible cause) via lspci:
