Help with Dell Constellation HDD

Hi, I bought a used Dell constellation HDD from eBay. Here's the link for the listing.

It's supposed to be tested by them, but when I received it, it didn't spin up. I tried putting it inside my Lenovo ThinkCentre M900 Tiny, and also tried using an external SATA to USB adapter, but none of them work.

Now, it's a bit weird and different from the usual HDDs. It's 2.5 inch, but thicker than usual, 7200 RPM, and is supposed to be enterprise grade. So maybe I'm doing something wrong, and need a special adapter for it. Or it can be a faulty drive. I'm not sure. If anyone has experience with these drives, please let me know if I should be doing something different. Thanks.
