[...] At least you missed the filesystem used for CDRW: UDF. Again maybe the function you are concerned about will call that CDFS or billfs. But now you know that you need to ask someone with a CDRW drive to check what the function returns for that drive.
I just formatted a CDRW with Ahead InCD and Windows XP reports "FS_UDF" as the filesystem.. (note, that WinXP still reports "NTFS", "FAT" and "CDFS"; it seems as UDF is the only filesystem where "FS_" is prefixed to the name..)
