Sugiro dar uma olhada na man page do reiserfsck, em especial os exit
codes, --scan-whole-partition e observar isso:

      6. If the reiserfsck --rebuild-tree step fails or does not recover what
      you  expected,  please  submit  this as a bug report. Try to provide as
      much information as possible including your platform and  Linux  kernel
      version. We will try to help solve the problem.
