Impossible de redimensionner les partitions

Salut à tous,

voilà presque 1an que je suis sous Linux avec Ubuntu, j'ai fais quelques erreurs puisque je connaissais pas vraiment, et là j'aimerais faire un truc clean, effacer ma partition d'Ubuntu, et installer la version 10.04.

Là je suis en Live CD et impossible de redimensionner les partitions, qui sont dans cet été (pas joli à voir) :
http://ups.imagup.com/09/1273286553.png

En gros :
- sda1 est la partion de restitutions de Windows Vista
- sda2 est Vista
- sda3 est la partition de mes fichiers
- sda4 Uubuntu

Je voudrais donc "décaller" sda3 pour enlever ce vilain trou, augmenter sa taille, et laisser à la fin 25Gb pour installer Ubuntu.

Seulement avec GPArted quand je lance l'éxécution de ces tâches j'ai ce message d'erreur :
"An error occurred while applying the operations"

Pour le rapport d'erreur en détail :

NTFS is inconsistent. Run chkdsk /f on Windows then reboot it TWICE!
The usage of the /f parameter is very IMPORTANT! No modification was
and will be made to NTFS by this software until it gets repaired.

========================================
Grow /dev/sda3 from 322.36 GiB to 334.36 GiB

Que faire?
Merci !
