Hi, Hope someone can help. I've spent about 3 hours (and a hundred bucks) on the phone with HP support, with no solution.
I have an HP Pavilion laptop, running Vista 32 bit, SP2. My optical drive, a DVD/CD read/write device, has worked fine for the past couple of years. Tonight, for the first time in a couple months, I attempted to watch a DVD. The DVD would not "load"--that is, when I put it in the drive, the drive's light flashed, and I could hear it spin--but nothing happened. The auto run window did not pop up. I then tried an audio CD--with the same results. I then tried a program disc (a card game)--and while it appeared a bit slow, it loaded and installed the software just fine.
Device manager says that everything is ok with the drive. (See attached screen shot). I have tried uninstalling and reinstalling the driver--to no avail. Vista says there is no updated driver available, and I can't find one on the HP web site.
Searching the web, I found several posts relative to deleting the upper and lower filters in the registry. I did this (and unfortunately screwed up the registry back-up)--it did not resolve the problem, but broke my iTunes program. (It complains that these settings are missing). I ran the Microsoft "Fix It" tool found at:
It said it found problems, but could not fix them.
During my time on the phone with HP, we did some tests with the command prompt--a list volume (?). When I had a DVD or audio CD in the drive, it indicated "no media" under status. When I put the program disc in, it listed status as "healthy".
When I attempt to launch Roxio Creator Basic--I get an error note that all my drives are "disabled". As I noted above, Device Manager says they are OK. (And I have tried disabling and enabling it in Device Manager). When I run iTunes diagnostics, it says it finds my drive, but there is no media in it (there is).
I have loaded various software packages over the past several months--so I assume that something I loaded is conflicting with the optical drive.
I've also "repaired" and updated my copy of iTunes. Again, to no avial.
The HP rep suggested a total restore --to out of box condition. I would very much like to avoid this.
I've also tried to restore from a couple of month old restore points--but both of the restores failed for "unspecified" reasons.
I'd appreciate any suggestions on what to do next, or where to look.
