My computer has two optical drives, I: and J: (a "combo" drive and a DVD
burner). Both show up normally in "My Computer".

I just reinstalled Windows XP SP2 (1st time since it came out in 2001),
and I'm having a strange problem: When I put a disc into them, nothing
happens. Not only is there no "autorun", but the label of the disc
media inserted and it's Icon (if any) doesn't even show up "My Computer"
(replacing "DVD/CD-RW Drive" as the Icon label, and the drive Icon).

It's not a hardware problem, as I still have the older smaller hard
drive with the old system on it (also WinXP SP2), and in that system
things worked (and still work) normally if I change the hard drive.

I've removed (uninstalled) the drives, shut down and let Windows
redetect them, that didn't fix it.

I've tried to find every "Autorun" setting I could, including the ones
in "Tweakui", but they are all set correctly.

I think that the problem is not that Autorun is turned off, but that
Windows isn't even seeing that media has been changed or inserted, based
on the fact that neither the Icon nor the Icon label in "My Computer" is
not changing from the drive type to the media label. In Windows 98,
there was a function called "Auto Insert Notification" which controlled
whether the drive was queried (polled) about once a second to see if the
media in the drive had been changed. It's acting like that is turned
off, but I can find no such setting in Windows XP (SP2, fully updated).

Note that the drives do work normally; if I click on the drive Icon, I
can fully access and use the drives in any normal manner, but Windows is
not recognizing the insertion of or changing of media in the drives
until there is a manual access. The drives themselves do recognize when
media is inserted, the drive lights flash briefly and the drives "spin
up". But the insertion or change of media doesn't seem to be being
detected by Windows.

Anyone have a fix?
