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
