WD My Passport HDD to be initialized
the HDD is one of my old: already used on my iMac OS Snow Leopard; today, new Catalina OS (neither Finder or Disk Utility SOS/initialize)don't recognizes it.
using Terminal I have identified it as disk3; The command "diskutil eraseDisk ExFAT /dev/disk3" (APFS as well) launches the process, And eventually returns "Error: -69760: Unable to write to the last block of the device".
is there any chance but throwing the device away?
