Uso MacBook Air Mid 2013 (Intel Core i5 a 1,3 GHz, DDR3 Intel a 4 GB 1600 MHz, Intel HD Graphics 5000 1536 MB, memoria flash da 128 GB) con macOS Sierra 10.12

Ho un disco rigido esterno (Western Digital WD Elements per 1 TB USB3) che utilizzo per l'archiviazione esterna per file di grandi dimensioni. Partizionato in 2 partizioni: JUMBO (HFS +, 794,8 GB, crittografato) e JUMBO 2 (exFAT, 205,0 GB).
Il problema è che a volte (specialmente quando lo uso per uno o più giorni senza espulsione) quando espellisco il disco e poi ricollego non "monta". Posso vedere / utilizzare solo la partizione exFAT. Ho provato a smontare ed espellere tutto usando diskutil ma non aiuta.

Così, ho provato a smontare tutti i dischi (2, 3, 4) e poi espellerli:
$ diskutil unmountDisk force /dev/disk2
Forced unmount of all volumes on disk2 was successful
$ diskutil unmountDisk force /dev/disk3
Forced unmount of all volumes on disk3 was successful
$ diskutil unmountDisk force /dev/disk4
Forced unmount of all volumes on disk4 was successful
$ diskutil eject /dev/disk2
Disk /dev/disk2 ejected
$ diskutil eject /dev/disk3
Volume failed to eject
$ diskutil eject /dev/disk4
Disk /dev/disk4 ejected
Dopo questo, disconnetto il disco e ricevo questo:
$ diskutil list

Quindi, non posso liberarmene.
Il problema si risolve usando il riavvio, ma ho bisogno di farlo senza riavviare. Qualcuno ha qualche idea?
PS: Inoltre, ho dimenticato di menzionare che nessun programma sta utilizzando file dal disco:
$ lsof | grep "JUMBO"
non dà risultati.
UPD: Quindi, dopo il riavvio, l'unità ghost è scomparsa:
$ diskutil list

E dopo averlo collegato, è stato rilevato e montato automaticamente e tutto funziona come al solito:
