CD Doesn't Show Up When You Put It In

Here is my problem. Whenever I place a disc into the my Samsung
SH-S182M DVDRW/CDRW drive, the drive will spin but I cannot locate the contents of the disk via Windows Explorer. If I shutdown and reboot, the drive contents will show up. I tried uninstalling and reinstalling the drive/drivers. I moved the drive from the Secondary Master to the Primary Master IDE channel and confirmed that the BIOS can see it. The registry for Autoplay is enabled. I’m at a loss of what to do next. I recently reformatted and installed a clean copy of XP on my PC (Gateway 510 G Home Computer R4) all XP updates have been installed. I checked the manufactures website for updated drivers and I believe I am using the most current. Also, I ran AVG and nothing was found.

This drive was working normally on an older model Gateway using XP SP2.

Please help me.

I used a Microsoft bulletin and deleted the LowerFilters setting in the registry and it fixed my problem.
