That is almost right. It's not that you need to remove the drives, it's that you need to have the same set of drives plugged in as when you activated TurboTax. I had to plug mine back in to get it to skip the authentication. There was no consideration that users would have different external drives plugged in when they try to use TurboTax. This means I can only use my TurboTax on my desk at home because I have a bank of three large drives plugged in thru a port multiplexor attached to my laptop. That would be most impractical to carry around. Poor software design.
