All right. But the man page says that badblocks can provide a list of bad
blocks to mke2fs, that is, _before_ the filesystem is created.
I have a partition on which bad blocks appeared long after I created the
filesystem, do I have to recreate the filesystem or can I add the list of
(new) bad blocks somewhere to the existing list. And what if this is a
reiserfs?

(Sure the best option when new bad sectors appear on a disk is to buy a new
disk, but the problem seems to be stable so I want to continue with this
drive.)
