I'm running XP Pro, all updates installed.
Both of my internal cd/dvd drives no longer auto-detect when a disk has changed. Inserting or ejecting a disk leaves the drive icon and title unchanged, and even the properties of the drive (used/free space, file system, etc.) remain unchanged. You can still open the drive and the correct content will appear, though it will not auto-run, nor will it launch the right application. (e.g. if you insert an audio cd and double-click, it will open rather than playing the music.)
I have not yet found a way (9 months now!) to get windows to detect the new disk other than rebooting. I believe this is starting to cause some problems with some of the software I am using... for example, one cd-writing program keeps complaining that the disk I have inserted is read-only even though I have put in a blank (formatted or otherwise) disk.
Searching for solutions, I have tried restoring the autoplay properties to defaults, and deleting the drive from the device manager and letting windows reinstall the driver. Still no success.
Any help at all is appreciated!
