I should note also, I tried on both an XP and a Win7 PC.
On XP after phone reboots, a notification in the tray comes up with Verizon logo that asks if I want to install driver for Samsung...(a Verzion website comes up in a browser window that is spawned also)
Yes or no, tried both, I get the Verizon Road Block.
In Win7 I don't get the notification or the browser spawn but I do see that Android is grayed out when I look at the usb devices in the tray
I tried to modify move or delete these J drive files, then it says I don't have admin rights (although I'm the local machine admin).
