I bought a Samsung 2.5″ 80GB USB2.0/1.1 HDD with a general casing. When I connect it to my home PC (Pentium IV 1.7GHz 1GB RAM with USB2 Enhanced Host Controller), I got a USB1.1 connection. The same connection to my notebook (Dell Latitude D800) enables me a USB2.0 connection. I borrowed a few friends’ external HDDs’ with similar connectivity but manage a USB2.0 connection on both my home PC and notebook. I cannot understand why or is there something I have missed out, hence can anyone help?
