DVD-RW disks appear to be empty in Windows Explorer on a Windows XP Service Pack 2-based computer


Microsoft Windows XP Service Pack 2 (SP2) cannot read DVD-RW disks that use the Universal Disk Format (UDF) 2.00 defect management system. When you view the DVD contents by using Windows Explorer, you see an empty root folder.


This problem occurs if the UDF defect management system creates a sparing table that spans more than one sector on the DVD-RW disk. Windows XP SP2 cannot read a sparing table that is larger than one sector. Windows XP SP2 can recognize that a DVD is using UDF. However, Windows Explorer displays the contents of a DVD as an empty folder.
