The power supply line is useless without the one this Umlötet. Without modifications, the connected hard disk is destroyed my Banana Pi reversing the polarity of the supply voltage as in my case. In the photo you can see why. The lines between the connectors are not soldered together with the correct polarity. That may possibly go to other board, the banana pi it's definitely not because of this contrary to this cable manufacturer, holds the internationally established line colors. The occurring during commissioning high short-circuit current (the polarity) destroyed in my case have ordered also at Amazon 2.5 "hard disk before the power supply abschaltete due to overcurrent after a few seconds. This hard disk now has continuous short circuit and is thus no longer usable . For the price you can expect a working cable, without which one must turn Rumlöten Whoever replaces me the defective hard drive I'm going to have to ask Amazon as now continues ...: -.? ((
