Hi there. I've recently modified an internal hhd from an old computer to use it as an external hhd. To do so I bought a SATA to USB convertor, but when I received it, I found out that it needed a 12V 2A power supply. I don't have such power supply, so I decided to take my bench power supply to power it (I know). And to my suprise it worked, but today I made a mistake and shoot 16V into the adapter... I think the hhd turned into protection mode because the voltage dropped quickly after. When I try to power the hhd (with the correct voltage), the voltage drops again... Does anyone knows the problem and how to fix it?
