How to work around bad blocks?

[Dirk Leber <dirk.leber@web.de>]

Hello List,
I am the unhappy owner of a "corrupt" ReiserFS. All the other partitions on 
the same disk work fine, just this one seems to have some bad blocks. HEre 
are some outputs:

> mount /dev/hda4 /mnt/data2/
mount: wrong fs type, bad option, bad superblock on /dev/hda4,
       or too many mounted file systems

> reiserfsck --check
[no problem]

> reiserfsck --fix-fixable /dev/hda4
reiserfsck 3.6.2 (2002)
Will check consistency of the filesystem on /dev/hda4
Will fix what can be fixed w/o --rebuild-tree
Will put log info to 'stdout'

Do you want to run this program?[N/Yes] (note need to type Yes):Yes

bread: Cannot read a block # 7503872.


> badblocks -b 4096
[detects bad blocks 7503858 - 7503871]

Obviously the build-tree option also fails. The "How Reiser handles Bad 
blocks-FAQ" can only be considered a bad joke, since you need a degree in 
computer science AND a mountable filesystem for fooling the FS in that way. 

What I would like to do is, detecting the bad blocks, freeing them (accepting 
there content) rebuilding the tree (or not) and than mounting it while 
accepting that some files will be corrupt. 

What can I do?
