How to convert a FAT16 volume or a FAT32 volume to an NTFS file system in Windows XP
As stated by Microsoft themselves in this Knowledge base article:
The conversion to NTFS is a one-way process. After you convert a drive or a partition to NTFS, you cannot convert it back to FAT or to FAT32.

In this case, you must either restore your data from a backup, or reinstall your operating system and programs.
