Hi - I'm new here. I have had my Aspire for about two years and it seems to be functioning fine. The other day I bought a Toshiba external hard drive to store a huge backlog of work documents (real estate). The unit came with a 3.0 usb cord that says compatable with a 2.0. It plugs in fine. It even lights up saying it has power. However, the drive does not show up as a device or a destination. When I open my computer all that shows up is the Acer drive and the internal CD. This is an Aspire 5734Z. Am I doing something wrong? Is there a way to upgrade my port with a downloaded drive? Or do I need to install a physical new port? BTW the manual is 34 pages of 14+ different languages but the only "setup instructions" are a sketch of a laptop, a cord and a drive. Thank you! Lou
