This sounds wrong. Reiserfs's bad block handling is an ACKNOWLEDGED
problem by NameSys.

http://namesys.com/bad-block-handling.html

When I last tried ReiserFS a year ago (things may have changed, yadda
yadda), I had a 20GB filesystem on a drive that developed "3" bad
sectors (of 512 bytes each).

After getting an image using dd_rescue, I ran reiserfsck on the image.
After reiserfsck finished 98% of the filesystem was completely and
utterly mangled. 

Since I made a backup copy of the filesystem image before running fsck,
I painfully used a hexeditor to recover some important scripts that I
had written.

I won't use Reiserfs on a production box again until:

a) The bad block handling is fixed
b) The reiserfsck command becomes more robust

BTW, Reiserfs v4 looks interesting.
