Tengo un disco duro externo de 1TB. Fue utilizado como disco de respaldo para Time Machine. Pero a partir de un día, mi Mac no puede reconocerlo.
El problema puede deberse a que quité el disco sin expulsarlo primero.
Puedo ver el disco por diskutil list :
$diskutil list
.... This is it.
/dev/disk2 (external, physical):
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *1.0 TB disk2
1: EFI EFI 209.7 MB disk2s1
2: Apple_HFS Chang 999.9 GB disk2s2
$diskutil eject disk2
Volume timed out while waiting to eject
$diskutil unmount /dev/disk2
disk2 was already unmounted or it has a partitioning scheme so use "diskutil unmountDisk" instead
$diskutil unmountDisk /dev/disk2
Unmount of disk2 failed: at least one volume could not be unmounted
$diskutil mount /dev/disk2
Volume on disk2 timed out waiting to mount
$diskutil mountDisk /dev/disk2
One or more volume(s) failed to mount
Y los resultados:
