HD externe: MFT is corrupt, cannot read its unmapped extent

#1 Post by helloDeLu » 13 May 2014, 20:09

bonjour
Mon disque dur externe me fait des blagues: lorsque je le branche, linuxMint me dit "MFT is corrupt, cannot read its unmapped extent record 18".
J'ai exécuté testdisk, fait vraisemblablement une fausse manip mais qui n'est pas l'origine du problème (j'ai un message This partition ends after the disk limits.), rebuildé le boot sector et tenté de réparer la MFT mais sans succès.
Mon disque est il HS?
Merci pour vos lumières!
Christophe
