Anybody felt a slight electrical tingling when touching the casing of the HD-Pro when operating?

If you have a unit of the HD-Pro, you will know it has only a two-pin plug on its adapter, therefore no 'earth' for the plug. Since there is no 'earth' on the plug design, I am trying to find out whether the electrical leakage is by design or is my unit faulty as it is.

I don't think you understand what the 'earth' point on a plug is about. The 'earth' point on a plug serves as the grounding source for the electrical item in instances when there is power surge either through faulty internal components or from the power supply. Unless your unit comes with a three-pin plug as standard, then there is no difference whichever source the power plug is connected to, as there is only two pins on the plug for 'live' and 'neutral'.

Secondly, some computer component design uses the metal casing as a sort of grounding as well, similar to the concept of car batteries grounding on the car chassis. So, if this is indeed the design employed by the manufacturer on the HD-Pro, then it will be a normal instance to feel the slight electrical tingle depending on whether the person touching it is directly 'grounded' or not.

However, my question again is if there is anybody that has the similar experience, please do say so. I do not wish to make a hasty warranty claim from Yangxi, nor do I wish to risk the safety of my harddisk inside the HD-Pro in case this is a sign of it being faulty.

I have a Western Digital Caviar Green 1.5TB inside mine, casing feels about 35-40°C (using hand touch) while operating. Should not be a problem as harddisks are specified to run in conditions up to 50°C generally, plus the metal casing of HD-Pro should be good for dissipating heat.
