In short: I connected a 19V laptop power supply to my WD My Book 8TB, plugs are exactly the same.
Only 20 sec, but it killed the 12V drive.
Bougt in 2017-Nov.
Harddisk is: WD80EZZX-11CSGA0
Does anyone have any indications of typical damage and pitfalls?
I know the older threads here, but ask about this particular hard drive.
