The cable type USB 3.0 / y to Micro USB 3.0 is short, extremely rigid, and then bad also ... Disconnecting and reconnecting the random hard drive! :(
>>> A cross test leads with another USB 3.0 external drive, defined the cause.
In addition to being defective, the same cable that is blue rubber with bad aspect is not at all matched with red metal case and stainless steel color (Below).
In short, even if the cable if it works (Luckily?) Anyway it's a little carnival!
Ps: Connected with a real cable, functional and less unsightly it will all better result and transfer rates are here!
;)
