I may have screwed something up here, but here we go, I will try to explain. I recently bought a Western digital My Book essentials 4tb external hard drive. I bought it thinking I would get a 4 TB western digital branded hard drive for less, by buying the external enclosure in an all in one plastic enclosure, & later take it out of the plastic enclosure for the bare hard drive. I thought this was a good deal, as I saw quite a few bare 4 tb western digital hard drives that were much more expensive than one in an enclosure. So I got the 4 TB Western digital Mybook essentials, with USB 3.0, USB 2.0, in the black plastic enclosure. It felt flimsy, & I wanted the bare hard drive out of it, so I pried it out. It was not labeled a western digital but an HGST, it was actually a Hitachi deskstar. I then proceed to put it in my own enclosure, & connected it to my mac. I get a message saying the drive is unreadable, & was prompted to initialize it. I did an erase format in disk utility, now the untitled drive reads that it is only 1.8 TB! I then connected it to a windows PC, and the same thing, it was only 1.8 TB. What happened? I know I may have made a dumb move, is there any way I can get all 4 tb back again?
