Bad blocks on a ReiserFS volume. How to retrieve files?

Bad blocks on a ReiserFS volume. How to retrieve files?

I have a large hard-disk (120 GB) on which some blocks went bad.

Now, it cannot be mounted.  Attached is what debugreiserfs says.  What
can I do; I'm newbie to reiserfs architecture.  I thought that ReiserFS
keeps copies of the superblock or something, like ext2/3 does.

reiserfsck says "error occured looks like hardware problem.  bread
cannot read block 13271040".  That's the actual number it displays.


PS I have asked the same question on the reiserfs-list, but it's 
extremely low traffic.  Maybe someone here knows more.

Thank you
