Quando si crea una partizione con GUID Partition Map Scheme in Utility Disco, viene visualizzato il messaggio "La partizione non è riuscita con l'errore: impossibile scrivere nell'ultimo blocco del dispositivo". Lo stesso messaggio quando provo a cancellare l'intero volume. Lo stesso vale per la formattazione per Mac OS Esteso Encrypted .
Cercando di scrivi a il disco da / dev / random prima della formattazione non cambia nulla.
Riempimento con zeri:
$ sudo dd if=/dev/zero of=/dev/disk1
dd: /dev/disk1: Resource busy
... e successivi:
$ sudo dd if=/dev/zero of=/dev/disk1
dd: /dev/disk1: Input/output error
1+0 records in
0+0 records out
0 bytes transferred in 0.250087 secs (0 bytes/sec)
Esecuzione di diskutil:
$ diskutil eraseDisk JHFS+ "ext" /dev/disk1
Started erase on disk1
Unmounting disk
Error: -69760: Unable to write to the last block of the device
Dopo tutto ciò, Windows vede il disco come un volume HFS vuoto, ma quando provo a riformattarlo con Windows Explorer, riporta: "Windows was unable to complete the format"
.
Usando diskpart sotto Windows, " formato "l'azione è rimasta bloccata allo 0% per 2 ore (che per un aspetto da 500 GB dovrebbe essere definitivamente" congelato "):
DISKPART> clean
DiskPart succeeded in cleaning the disk.
DISKPART> create partition primary
