In every ThinkPad I've opened up there was no switch, no electrical 
connection at all, to the bay eject lever. Thus there is no way that 
anything except the user can know that the latch has been operated and 
the eject lever is out. Things may have changed in the newest ThinkPads, 
I have not opened any of them, but I would guess not. That's why the 
procedure under any operating system is: 1, you tell the system you want 
to remove the device in the bay; 2, the system prepares the device for 
removal and then turns off the LED beside the bay; then 3, you can pull 
on the lever and remove the device.
