About 13 days ago I got a Western Digitial 5TB external drive.  Soon I started getting messages "USB device not recognized" and it would disappear from my computer.  If I unplugged it and plugged it back in it shows up again - for a while.  Then I got a CRC error message. I tried it in two different USB ports and two different USB cables. I called WD and they wanted to replace the power supply.  Anyhow, the errors continued, so I got a RMA.  I got the replacement yesterday, and now I've gotten a "USB Device not recognised" error again.  I have it set to not go to sleep. I'm using Windows 10 on an HP i7 that is a few months old. A Seagate external drive that I've had for a couple of years is working OK.


What could the problem be?

1- Does it have an installer? or are you connecting directly. Large External drives have a driver.

2- I also read that it could be that the power supply does not supply enough power so use another 

    external USB hub that has a power plug of its own. Let me know I also have this issue with a drive

    I was working on..reminds me I have to go back and try this...LOL Thanks
