This is a bad block on the hard drive.  Vitaly, the newer fscks give 
instructions about bad blocks, yes?

Stephen, you can read our faq and act accordingly, or pay $25 and we'll 
handle everything for you if you give a login or provide personalized 
instructions otherwise (but workday is over for today....)

reiserfsck

[Peter Herklotz]

Hello,

how would I know which version of fs 3.5 I use(d)? The filesystem on
that partition was created using SuSE Linux 7.3.
If I made a wrong choice of the superblock version using "reiserfsck
--rebuild-sb" can I correct it afterwards?
At the moment "reiserfsck --rebuild-tree" does not find ANY data on
the partition. It is telling me
'Could not find hash in use. Using "r5"
"r5" hash is selected'

and then doesn't find anything.
  
I am quite clueless what to try now.

Thanks
Peter

Could you tell what you answered here

what is version of ReiserFS you use[1-4]
  (1)   3.6.x
  (2) >=3.5.9
  (3) < 3.5.9 converted to new format
  (4) < 3.5.9
  (X)   exit

If you mkreiserfs by default from SuSe 7.3 you should have >=3.5.9.
It would be easy to say what is going on if you send the reiserfsck 
output and its logfile (-l option). 

Let's check whether you have some data on the partition or not. Could you 
run ./debugreiserfs/debugreiserfs -D /dev/hdb3 > hdb3.meta
If it prints a lot of LEAF NODEs, you have.
