I have the 1 Gb Passport Se USB 3.0. Using Gigabyte MB and Win7 Ult 64bit, 8Gb ram.
When using the drive on USB 3 0 port, after a while, the pc will make that sound as if something was plugged in/out of a USB port. Then in a few seconds, whatever I was doing on this drive will freeze. I am using USB 3 cable, connections are secure and latest USB 3 drivers for MB. Occasionally when I connect the drive to USB 3 port, I will get the message that this device will perform better if connected to a USB 3 port. Most of the time I am watching movies off the drive. I have turned off the power down setting in Device Manager for the controllers,
This only happens on my USB 3 port. Doesn’t seem to happen on the USB 2 or on laptop USB 2.
