I am a prowd owner of an i7 book. Unfortunately I am having problems connecting my seagate 1TB slim harddrive . I connect the HD with the USB port in the keyboard.
After a long wait windows recognizes the HD. However, when trying to open files it freezes constantly.
In my experience you’re better off using the usb3 cable delivered with the laptop, not only will it be much faster (the keyboard uses USB2 I thought), I also think it is better able to power the drive this way. Don’t ask me why but this is from personal experience with the tablet
I am not sure what type of USB the Keyboard has. However connecting to the USB 3.0 port on the tablet is much faster. I am not sure this is going to resolve your issue though. File should open from either USB port.
