My mount points are /mnt/sda, /mnt/sdb1, /mnt/sdc, and /mnt/sdd. These were allready there.

sda and sdd, I don't care about, they are the memory stick and smart media slots respectively, I don't use that kind of card. sdb is listed with a 1 because there was a card there durrnig my most recent reinstall, so it saw that there was one partition, it's entries are the same as the ones for knoppix via CD. sdc has everything but mounting set to auto in the fstab, so which ever is correct, "should" work.

as root, I entered
mount -t auto /dev/sdb1 /mnt/sdb1
response was "mount: /dev/sdb1 is not a valid block device"

Then I tried
mount -t auto /dev/sdc /mnt/sdb
response was "mount: /dev/sdc is not a valid block device"

This is the same error I get when trying to mount with kde or with that block mounter app that sits in the tray.
