You've made four mistakes indeed.

You're doing it wrong - /dev/sdb1/ implies /dev/sdb1 is a directory,
and it's a block device.

Same thing.

While dd can be used to copy a directory, it cannot be used alone for
this task. Try this:

(cd /var/www; tar cf - *) | (cd /media/lin50; tar xf -)

Or, just:

cp -a /var/www/* /media/lin50
