problema ao montar hd externo

[Deckardbot <deckardbot@gmail.com>]

Olá

Tenho um hd externo formatado com NTFS.
Nunca tive problemas para montá-lo, porem depois de formatar meu Squeeze ocorre o erro:

Error mounting: mount exited with exit code 1: helper failed with:
Error opening '/dev/sdb1': Permission denied
Failed to mount '/dev/sdb1': Permission denied
Please check '/dev/sdb1' and the ntfs-3g binary permissions,
and the mounting user ID. More explanation is provided at
http://ntfs-3g.org/support.html#unprivileged

Mas estou no grupo FUSE.
$ groups
user adm dialout fax cdrom floppy tape audio dip video plugdev netdev bluetooth lpadmin fuse scanner

Alguem pode ajudar?
