Can Not Connect to My Book Home Edition

I can not connect to my Home Book Edition.  I am running Vista Home Premium.  Over the past months, when I plug the drive into my computer (using fire wire) the amount of time for the drive to appear has gotten longer and longer.  Today it took forever to get a connection, then the light on the Home Book went out and I lost the connection.  Although I turned the Home Book back on and the light is on, I can not longer connect to it.  Any suggestions would be appreciatated.

Try using DLG to run a test.
