Well I guess I was one of the unlucky ones, mine just turned up...plugged it in and it's not detected, tried in both my laptop and an external enclosure and fails to detect.
Pretty gutted it's DOA, I guess I'll start a RMA.
Just get in touch, we will check it and if DOA get it swapped straight out. If you ask us too as well we will happily pre-test the replacement as long as you understand it will be opened, upto you.

We sold over 1000 in 24hrs gonna be the odd duffer just like any product.
