I leave my computer for downloading and when I get back I see the external HDD and qbittorrent are frozen.

OS : Windows 10 64-bit Version 1809

1) I updated all the drivers via “Driver Booster”


2) I adjusted “USB selective suspend setting”
Power & Sleep Settings – Related Settings – Additional Power Settings – Change Plan Settings – Change Advanced Power Settings – USB Settings – USB selective suspend setting – Plugged In – Disabled

3) I unchecked the setting “Allow the computer to turn off this device to save power” for all the items in the areas;
+ Device Manager – Universal Serial Bus Controllers
+ Device Manager – Human Interface Devices


4) I adjusted “Power buttons and lid” setting.
Power buttons and lid – Lid close action – Plugged In – Do Nothing

5) I adjusted “Sleep button action” setting.
Power buttons and lid – Sleep button action – Plugged In – Do Nothing



Any ideas how to fix this?

only qtbittorrent and HDD or System Hang ???

1) When I unplug the external HDD and download into internal HDD qbittorrent does not freezes.

2) When the external HDD is plugged and qbittorrent is not running. The external HDD does not freezes.

What's the problem and how to fix that?

I found the answer.
