Pb reiserfs / Debian

Bonjour,
Petit soucis avec mon FS ...
J'essaie de faire un reiserfsck complet mais je n'y arrive pas :

bash-2.05a$ sudo reiserfsck --check /dev/hda -l log_reiserfs
reiserfsck 3.6.17 (2003 www.namesys.com)
Do you want to run this program?[N/Yes] (note need to type Yes if you do):Yes

Replaying journal..
No transactions found
Checking internal tree..
Bad root block 0. (--rebuild-tree did not complete)

Si je fais un --rebuild-tree :

Skipping 4388 blocks (super block, journal, bitmaps) 7600962 blocks will
