XP: Converting filesystems.
Posted by cascadehush on October 5, 2006
You can convert a FAT or FAT32 volume to an NTFS volume without formatting the volume, though it is still a good idea to back up your data before you convert.
Once you know how, it is easy to convert a FAT32 filesystem to NTFS. If you ever have to restore an older system from a recovery CD/partitionr, you will often end up with a FAT32 boot partition. Some laptops currently still ship with FAT32 partitions by default. As this article explains, XP has a utility to do the conversion without the need for a reformat, or 3rd party utilities.
