WD Essential 1600B014 - no power after WIN10 20HS2 update

Good Day. I hope you can help. I use this drive now only as a storage device and so only plug into PC when retrieving old files; it’s been a while since I last accessed it and inbetweentimes WIN 10 has been updated. Is it just a coincidence that the unit no longer functions? I’ve connected both the USB and the power. No power light, no sound and no device showing. Before I search for a replacement power unit is it possible that WIN has caused the problem? I’d appreciate some advice please. Thank you.

Very doubtful, try it on another PC to verify.

Many thanks GDB: hadn’t thought of that. Indeed it works on another PC
so it’s a bit of a puzzle but at least the Drive still functions - relief.
