Ghost Icon for USB Toshiba External Hard Drive

Hello,

I have a 160 Gig Toshiba USB external hard drive that is working fine.
However, instead of getting an external hard drive icon I am getting that
strange looking 'ghost' icon that Windows uses when it does not recognize the
device it is connected to. I am running Windows Vista Home Premium. I am
able to save and move files back and forth to and from my local disk c:.
This ghost icon is annoying and it is telling me that something is wrong at
the application layer I would say because it is not telling the physical
layer what the external hard drive is. How could I fix this? BTW I cannot
even change the icon by right clicking and going into properties, there is no
option to change the icon.
