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?
