Hi,

1. pls check buy plugging in some other pen drive or other usb device and check same power off happens after ten mins. If it is so, then the problem is with ur usb drive. Servicing might be needed.

2. If the above device works fine even after 10 mins, then the problem is with ur hard drive controller. You have to reach out to a service station or replace the controller.

3. If you are sure that the problem is not because of the above 2 scenarios, pls reply back

Thanks.
