I have the same problem. I have a Dell Vostro 1700 Laptop running Vista
Business (installed by DELL) that will not read any DVD's or CD's. The
drivers are also correct and I checked the registry keys listed in the MS
article below. The upper and lower filters where not there. I have tried
using a different internal optical drive and an external USB DVD Drive with
the same results. After testing with multiple optical drives and multiple
disks, Windows states that the media is in an unrecognized format. In Device
Manager, media comes up as RAW format. The problem does not appear to be
related to CDFS format itself. From the Vista system, I can access a remote
CD-ROM drive that is shared off of a different computer. However, when I try
to access the shared CD-ROM on the Vista machine from another computer, I get
a message stating that the disk is not formatted or the contents are corrupt.
After testing many different optical drives on this system, it does not
appear to be hardware related or a driver issue. Any assistance would be
