As the topic says ... I just added a new hard drive to my computer. Its a 3TB WD green drive , just like one of the other green drives in my computer . Here's the thing . This drive seems to have a partition already on it. When I go to disk management under windows 10 currently , it lists the new drive as disk 1 2794.52 , 2048gb unallocated and 746.52 unallocated ( this is the new drive )... my other WD green drive , formatted and came from win 7 , lists that drive as 2794.52 129mb unallocated and 2794.39 as healthy. These are both the same types of drives .. Only difference is I bought the second one from tiger direct years ago and it came in the proper box etc. The new one I bought from amazon and I'm not liking the way it was packaged not to mention it was missing a sata cable and documentation. I'm not sure if this could be a knock off drive or could be something newer ...need some thoughts on how to proceed. FYI , it appeared to be factory sealed and the drive was highly rated The last image will show what I'm talking about ... These are both WD green drives ... Why is the new showing up like this ?
