mount: can't find /dev/sda1 in /etc/fstab or /etc/mtab

Made some upgrades on my KDE 3.5/ 9.3 and suddenly I have problems with my USB card reader. Remember from some versions earlier that the easiest way would be to restart the computer and the usb devices which would be inserted would be included in the fstab. Must have slept through some developments. Went googling but did not find an answer. Can somebody help?
