This article describes the ability of Microsoft Windows XP to support the DVD-RAM file systems.
In Windows XP, DVD-RAM disks can be used as either CD-ROM/DVD-ROM devices or as rewriteable disks. The support technology for DVD-RAM uses the file allocation table 32 (FAT32) file system for read/write operations and enables the use of the Universal Disk Format (UDF) file system for read-only operations. DVD-RAM also supports multiple-session recording and logical block addressing.
The following list contains the DVD-RAM drives that are supported in Windows XP:
Note Universal File System Driver (UDFS) has a writable path in Windows XP to support volume writes to format UDF to Fat32. If the media is formatted to the CDFS (9660.x) specification, Windows XP does not have a write path, and the media will be perceived as read-only.
