I ordered the kit late last week and was fearing the worst today when it arrived after reading this thread.

I initially connected it to my Windows desk top PC and checked in disk management and it was OK reading as a 1Tb drive.

So this looks like an issue with only some of the current stock I guess.

I have now connected it to a Pi 2 and transferred the root storage from the SD Card to the drive which is working as expected.

Hope you guys get to the bottom of the problem and get your drives fixed.
