I just got a 12 TB WD Easystore drive and I have a minor issue with the 12V power. The 12V power supply that I keep permanently plugged in doesn't work with this drive. The center pin in the power receptacle in the drive case is too fat to accept the 12V power supply that I use with every other 3.5" drive case or drive dock. I use different 3.5" drives in ext. cases or in my drive dock and this one power supply works with all of them except the new WD Easystore drive. The power plug for the WD's power supply fits loosely, not snugly, in the power receptacles of some of these cases. More importantly, the WD power supply is only 1.5A. The dual bay drive dock came with a 3.0A power supply, and that's the one I keep permanently plugged in. As I said, a minor issue. I use 1 drive a year for my backups, and I'll probably buy the same drive next year. I got this drive on a Black Friday sale at $100 off the regular price, and less than the price for a 10 TB drive.
