What was delivered was a perfectly packed genuine HDD, in sealed box. Offers standard 931 GB space. There is a HTML file inside, on clicking which you are taken to online product-registration. I registered and received 3 years (and 40 days) warranty.
From the beginning, the USB cable gave trouble with the USB 3.0 port (HP laptop, Windows 8.1). OS didn't recognize the HDD. I tried one USB 2.0 port, and it was readily recognized. Confused, I retried the USB 3.0 port many times, and finally after lot of fiddling, it was recognized. Even now, every connection to 3.0 port is a lot of hassle - I have to plug/unplug for a while to get it connected. Must be some cable issue. Not sure if it's worth the trouble to run around for warranty cover on this - let's see.
HDD is working fine otherwise. HDD is good and solid. Looks rather expensive. On 3.0 port, speed is about 30 MBPS or less. I transferred 250 GB - not much heating noticed. There's a very nice matte-feel cushy plastic cover - it certainly will not slip from your hand that easily. The data cable is longer than expected - over 18 inches including the sockets - that's over 1.5 foot! This is so much longer than my Seagate HDD.
