Usb Medion hdd keeps losing connection

Hi,
I have a 1000 GB usb hdd from Medion, formatted in NTFS, assigned driveletter J in diskmanagement. My problem is that the drive keeps losing connection to my laptop all the time., so I have to power up again. I do not recall this as a problem with earlier versions of windows, I have disabled the possibility to power off the usb drive when idle in power management, and have tried to remove usb drivers, sadly no luck, usb drive keeps losing connection. It is a usb 2.0 drive, connected directly to laptop G750JH with Usb3.0, win 10 version 1607. Could anybody help please? Thankful for reply,
kind regards,
Stephen Halck

Assuming the HDD is powered via USB it may be short of power, try using a micro b splitter cable

Hi again,
thanks for the answer. My usb drive has a seperate power connection to the wall.

Are you able test against a different PC, this will prove/disprove the HDD?

Yes, hdd works fine on my other laptop with win 7, I even took hdd with usb and power unit down to a store, they plugged the hdd in a computer, and it of course worked perfectly

Hi,
thanks for the answer. I already have power disabled, as I tried to write in my initial post.
Kind regards,
Stephen

have you tried a different USB cable/port?

Yes, I have.

Check for BIOS updates. Chipset drivers as well. Doesn't hurt to reinstall the latest chipset drivers as well. Also if any different when laptop plugged in or not.
