ME is like windows 2000[not 98].

I don't know if the KN7000 acts the same, but when I use my portable hard drive with my computers, even though they are USB 2.0, the portable hard drive is high speed and needs the high speed USB connection port...The transfer speed is super fast compared to the port that is not high speed..
For example on the slower port an 8 or 9 minute transfer only takes about 30-40 seconds on high speed port..

My laptop will give an notice if it is not connected to the high speed port..
