If you want windows to recognize it as soon as you plug it in without having to go through DISK MGMT is to :
First recognize the Drive through DISK MGMT and assign it a drive letter
Then go to COMPUTER select the removable drive then (right click) then (properties)
Select (hardware)
Find your harddrive in the list then select it, then click (properties), then (policies)
Select (better performance) and not (quick removal)
Thats it.. you will have to use the (Safely Remove Hardware) icon in your system tray before removing this drive from now on to make sure there is nothing in the cache waiting to be written, but that only takes a few seconds, and saves the BIG TO DO of DISK MGMT everytime you plug it in...
