I brought my Vista machine out of hibernation this morning to discover that the physical DVD-RW drive had disappeared from My Computer. In fact, the virtual CD-ROM drive provided by Daemon Tools had disappeared, too. After a typical round of troubleshooting (reboot, check bios, uninstall driver from Device Management and reboot, etc) followed by a brief googling I discovered the solution below.
The solution comes from this post on The Vista Forums (unofficial) website. It turns out some kind of strange registry mishap occurs and the Windows CD-ROM (cdrom.sys / cdrom.inf) drivers decide not to load anymore. When you look at the Device Manager, you'll see the yellow warning (!) icon in front of the CD/DVD ROM devices; when double clicking them you'll be greeted with the error "Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)".
Luckily, the solution is painless and simple: just import this registry file to fix the problem (code below):
Update (2007-11-29):After looking through my Event Viewer today I noticed the following error in the System logs:
"The following boot-start or system-start driver(s) failed to load:
PxHlpa64"
Quick googling took me to Microsfot KB314060, which mentions the above fix for this problem. So if you'd rather get this from the horses mouth than here at the reliable and trustworthy OSJ, be my guest. :)

my drive wants to re-format everything
I tried the regedit procedure above and it did not fix my problem. My drive wants to format every CD that I put into it. I cannot view files on the CD. It automatically wants to re-format it. How do I fix this?

Thank you OSJ :)
disappearing cd-rom/dvdr drive
I had this problem but it seems to have partially corrected itself. the dvdr still shows up but not the cd-rom drive. however, cds still play in my media player with auto play. any idea how to fix that? or should i just try the suggestion?
Matshita DVD/CDRW UJDA 770 ATA Device disappers in Vista.
After I login, the DVD/CD drive appears as two DVD/CD drives, then they both disappear. When I checked for "driver details" it states that no information can be found for this device. When I check for the driver type, it shows as "pxhelp20.sys" for the CD Rom driver. When I first log in, the drives appear, but when I try to install software, it will install partially, then the drives disappear, leaving me with an incomplete installation. Any answers? Please email me at trwhas@yahoo.com Thanks!
