Hi, first time on these boards.

I've just upgraded to Vista and I'm having a problem where my nec dvd_rw
nd-4551a drive will not recognise that there is a disc in it. If I start up
with a disc in, it works but If I start with no disc in it doesn't. According
to the system the drivers are up to date so I can't get my head around the
problem. It was workin perfectly before the upgrade.

I can obviously get by, by just making sure their is a disc in when I boot
up but it is not an ideal situation, Any help would be greatly appreciated.
