#Unplug all connectors from the drive at least 30 minutes before testing as residue voltages may disturb this test and pose a danger. After 30 minutes fully disconnected, ensure that [[Power supply safe discharging|voltage has been safely discharged]].

{{tip|As D19 is a protection device, drive works without it as well, so it is possible to repair the drive just by removing D19. However without the diode, rest of the electronics inside drive are vulnerable to the same error that caused D19 to burn. Operating without D19 will always terminate warranty.}}
