I purchased this external drive end December 2010, four months later he was no longer working, or 1.5 TO of lost data .. This drive operates with software used, among other backups, so permanently connected equipment, or from a technician that's what would have caused his sudden perte..Tout disk is found write-protected, you can buy more initialiser..bref the less sophisticated disk, for me it's the 1st time an external drive let go ..
