Thumbs up Bad root block 0. (--rebuild-tree did not complete)


Hi everybody

I have come to the end of my knowings on how to fix my reiserfs volume:
Will check superblock and rebuild it if needed
Will put log info to 'stdout'

Do you want to run this program?[N/Yes] (note need to type Yes if you do):Yes
rebuild-sb: wrong tree height occured (65535), zeroed
Reiserfs super block in block 8 on 0xfe15 of format 3.6 with standard journal
Count of blocks on the device: 39070720
Number of bitmaps: 597
Blocksize: 8192
Free blocks (count of blocks - used [journal, bitmaps, data, reserved] blocks): 39070720
Root block: 0
Filesystem is NOT clean
Tree height: 0
Hash function used to sort names: "r5"
Objectid map size 2, max 1996
Journal parameters:
Device [0x0]
Magic [0x0]
Size 8193 blocks (including 1 for journal header) (first block 10)
Max transaction length 1024 blocks
Max batch size 900 blocks
Max commit age 30
Blocks reserved by journal: 0
Fs state field: 0xfa03:
FATAL corruptions exist.
some corruptions exist.
sb_version: 2
inode generation number: 0
UUID: e8d0666e-9ebc-47fc-a33d-ff24ae50f621
LABEL:
Set flags in SB:
Is this ok ? (y/n)[n]: y
The fs may still be unconsistent. Run reiserfsck --check.

and then :

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

Replaying journal..

Checking internal tree..

Bad root block 0. (--rebuild-tree did not complete)

Aborted

and then :
No reiserfs metadata found. If you are sure that you had the reiserfs
on this partition, then the start of the partition might be changed
or all data were wiped out. The start of the partition may get changed
by a partitioner if you have used one. Then you probably rebuilt the
superblock as there was no one. Zero the block at 64K offset from the
start of the partition (a new super block you have just built) and try
to move the start of the partition a few cylinders aside and check if
debugreiserfs /dev/xxx detects a reiserfs super block. If it does this
is likely to be the right super block version.
If this makes you nervous, try *deletedurl*, and for
$25 the author of fsck, or a colleague if he is out, will step you
through it all.

Aborted

when --rebuild-tree was done... so now I am here still with hope on how to get metadata superblock or whatever corrected.... Please you guys , everybody - give me some tips that may leed me to save this hdd's content .... I have worked alot for the stuff that i have on this hdd , so I would love to get it back - oartially or full , ofcourse with errors after running all these check ... but still having the most parts of it intact

Thanks alot guys
From a sunny Sweden
