Hi Scott,

I have a customer's laptop:

Dell Studio 17/1745
Service Tag: BDW1RK1
Core 2 Duo 2.2 GHz
4 GB RAM
500 GB HDD
ODD = Optiarc DVD+RW AD-7640S
MB = 0G914P A04
Windows 7 Home Premium 64 bit
PowerDVD v.8.3.5424

Customer said it wouldn't detect and play CD audio disks, won't recognize or burn to DVD-R media and has an intermittant buzz in the audio when playing DVD movies.

Naturally I couldn't get it to buzz when I played a movie.
The drive shows the audio files on a CD audio disk but refuses to actually play them either through iTunes or Windows Media Center.
I can burn files just fine to a DVD+R media.

The latest BIOS and drivers are installed. I'm leaning towards a bad ODD but I'm not sure since many of the functions of the ODD are still working great.

Any ideas?

Those symptoms could be caused by hardware or software. To eliminate the software, boot from a liveCD like the Ultimate Boot CD for Windows and test the drive to see if it works properly. If it does work properly then the problem is in the original software (OS/drivers/config), if not then the drive is most likely defective. Scott.

Thanks Scott. While I was downloading UBCD I checked out U&R Laptops 2nd ed. Top of page 489 said to disable ODD in Device Manager and allow Windows to reinstall drivers. I did that and audio CD's will now play, although without autoplay.
Upon more research I found that the audio distortion (raspy beeps) is a known issue with Dell and the service rep said they are working on new drivers for the wireless card to fix it. Wireless card? Go figure! They don't know when they will be available though.
