disco rígido externo não montaria

Question

Por favor ajude

Estou procurando algumas respostas sobre esse problema, feito isso e aquilo, mas nada prevalece.

Eu tenho um disco rígido externo Toshiba 1 TB, que é dividido em dois volumes de partição (toshiba 1 & toshiba 2), formatados em Mac OS Extended Journaled

Algumas semanas atrás, o Toshiba 2 não montaria e não seria detectado. Eu corri o primeiro socorro e feedback como abaixo:

Repairing file system.
Checking Journaled HFS Plus volume.
Checking extents overflow file.
Checking catalog file.
Checking multi-linked files.
Checking catalog hierarchy.
Checking extended attributes file.
Checking volume bitmap.
The volume Toshiba 2 could not be verified completely.
File system check exit code is 8.
Updating boot support partitions for the volume as required.
File system verify or repair failed.
Operation failed…

Tentei o comando diskutil repairvolume, que é o feedback abaixo:

Também tentei sudo / sbin / fsck_hfs -drfy / dev / disk3s3, feedback como abaixo:

Como eu sei, o volume não pôde ser verificado completamente.
