I initally tried to erase a 200gb external, but it froze up disk utility...so I had to force quit it. So I rebooted and tried it again, but now when I try to erase or partition it gives this error...
Disk Erase Failed
Disk Erase failed with the error:
Unknown error: -20
anyone know ehat I can do to get this thing erased and partitioned?
