I recently got a hard drive from a friend, who used to have an AMIGA 500. It
says "GVP great valley productions" and "Impact series 2      A500-HD+"  on
it, and hooks into the side expansion port of my AMIGA 500. After starting
up my computer using workbench 1.3,  I coulden't find anyway to access it ,
and when I turn off the hard drive the computer freezes.  When I start up my
computer with it connected but not on, the power light flashes like when
there is a software error, but it does'nt go to a guru meditaion screen, it
just restarts the computer, and it happens all over again.
          Do I need any special software to use it, and if so, does anyone
know where to get it?

               Thank you.
