my Lenovo laptop with Windows 10 does this weird thing:

If I connect my external USB 3 hard drive to my USB 3 port and the computer is not completly turned off, the disc won't show up in Windows. After a clean boot (or a restart) the external drive shows up and works smoothly only until the next Sleep/Hibernation mode. What I tried so far:

  1. sfc /scannow
  2. use the laptop only with the power cord plugged in
  3. change the 'USB selective suspend' setting to Never
  4. use the Y cable for more power to the USB
  5. reinstall the USB drivers
  6. update BIOS

...and many others, but nothing helped yet.

Do you have any clue, what else can be wrong?

I have found a partial solution using the Y cable, but it is not what I've expected:

  1. connect drive to the cable
  2. connect the "power only" cable to the laptop
  3. wait at least 30 seconds (otherwise it will fail with "USB device not recognised" error)
  4. connect the "power & data" cable to the laptop

This is what currently works the best for me, but I know that it is not a proper bugfix.

I have a solution that worked for me. You have to turn on core isolation in windows 10. If there are incompatible drivers that doesn't let you turn on then you have to delete those drivers and turning on core isolations make my problem external hdd shows up only after restart has been solved. Now I can unplug and plug back and it shows up immediately. Here is a tutorial how to remove incompatible drivers https://www.youtube.com/watch?v=ElIauyfMO-k
