Computer is 6 years old....yea, I know that is old.   But it's the best I have.   Yes, the drive was working before Win 10 install.   I have done some reading about it and it looks like a person might need to do something in the registry.............nope, not me.  LOL    Don't know why it would have come unconnected but will look at that.  I will use hubby's laptop for the taxes......it is as slow as a snail....and figure out what I want to do.  
Thanks everyone, you are the best.
