The external hard drive connected to the usb 3.0 expansion card ( http://www.transcend-info.com/Products/No-283 )auto starts (power on) every time when i start the computer, when i shut down it power off my external hard drive .
How to disable this function?
I want to manualy turn on / off my external hard disk . ( WD elements 3tb )
I think i forgot to mention that the external drive has its on power supply and power on/off button.
When i connect to an usb 2.0 port this not happen .
If connected to usb3.0 it power on the hard drive when i turn on my pc, despite i dont turn
the external drive on (using the swith).
I looked in the power settings but there you have only the option to prevent the hd going in stand by.
Looked also in the bios but there i can only enable/disable the usb ust controller.
