SYMPTOMS
The Microsoft Windows CE .NET Compact Disc File System (CDFS) and Universal Disc File System (UDFS) driver may incorrectly try to mount unsupported volumes that are contained on CD-ROM media.



CAUSE
This problem occurs because the UDFS driver does not ignore Secondary Volume Descriptor (SVD) sectors that identify types of unsupported file systems. These types include El Torito boot volumes and Apple Macintosh volumes. The UDFS driver uses the last SVD, regardless of type, instead of using the last supported SVD. Therefore, whether this problem occurs depends on how the CD-ROM was created.
