... who did create those?

Do you see it? sdb1 (block 8,17) is /dev/sdb0 which is not correct. The
name sb0 is normally not used. Correct naming sequence is sdb, sb1,
sdb2, ...

... that is your trouble you try to mount (open) /dev/sdb1 which is
block device 8,18 and that device does not exist according to
you /proc/partitions output.

Correct your device file definitions.
