You just need to go into your Device Manager to turn off the "Safely Remove" function.
here I took a picture:
Open Device Manager, open Storage controllers, then just right click "Marvell 91xx...", choose properties, then go to the policies tab, and uncheck the box "Enable safely remove disk."
I would then reboot, to see the change.
Haven't been on this site for a log time, but when i was faced with this prob, googled & found your answear.
It solved my problem, Thanks.
