The ATV-16 is a "throw away" drive, there are no repairable parts, mostly because everything is integrated and when you separate them, they become unusable anyway. So there are no schematics or parts available.
Most cheap small drives are like that now, partly in recognition that the labor cost to repair them is greater than the replacement cost.
