Mount fails after reiserfsck --rebuild-tree failure

[KAA <kaa@viva-solutions.com>]

hi there!
I'm running into a real big problem with one of my servers.
Very important data contained on its /dev/md0 which is RAID1
consisting of /dev/hda & /dev/hdc - both 120GB Seagate Barrackuda IV
Yesterday I had one of drive replaced with exactly the same one because 
of it's failure. After that mdadm with no complaints synced array and I 
mounted it without any problems. Later that day I've noticed several 
errors like following one in syslog:
  vs-5150: search_by_key: invalid format found in block 6377300. Fsck?
Mar 17 13:23:44 gate kernel: vs-13070: reiserfs_read_locked_inode: i/o 
failure occurred trying to find stat data of [13247 14
Mar 17 13:23:44 gate kernel: is_tree_node: node level 0 does not match 
to the expected one 1

so I've unmounted array fsck'ed it (unfortunately didn't save output of 
first fsck but it failed and recommended to do --rebuild-tree)
since that time fsck --rebuild-tree /dev/md0 fails with the same error 
all the time:


reiserfsck 3.6.13 (2003 www.namesys.com)

*************************************************************
** Do not  run  the  program  with  --rebuild-tree  unless **
** something is broken and MAKE A BACKUP  before using it. **
** If you have bad sectors on a drive  it is usually a bad **
** idea to continue using it. Then you probably should get **
** a working hard drive, copy the file system from the bad **
** drive  to the good one -- dd_rescue is  a good tool for **
** that -- and only then run this program.                 **
** If you are using the latest reiserfsprogs and  it fails **
** please  email bug reports to reiserfs-list@namesys.com, **
** providing  as  much  information  as  possible --  your **
** hardware,  kernel,  patches,  settings,  all reiserfsck **
** messages  (including version),  the reiserfsck logfile, **
** check  the  syslog file  for  any  related information. **
** If you would like advice on using this program, support **
** is available  for $25 at  www.namesys.com/support.html. **

Will rebuild the filesystem (/dev/md0) tree
Will put log info to 'rebuild-tree.log'

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

The problem has occurred looks like a hardware problem (perhaps
memory). Send us the bug report only if the second run dies at
the same place with the same block number.

rebuild-tree.log contains three lines:

is there any way to get my data back?
thanks in advance!
