a: drive

I have a fresh install of version 6.
Now, when I turn on my computer and after the orange ball is done doing its thing and the system is secure, I hear the a: drive trying to be accessed. This is just before the monitor icon in the system try comes up showing my broadband is connected.

This did not happen in version 5.
any ideas?
Thank you.

hmmm, must be normal?

Is working now. Maybe an update fixed it?
