If you install Windows 2000 from a CD-ROM to a 20-gigabyte (GB) hard disk that uses the FAT32 file system, the installation succeeds. However, when you attempt to convert the file system to the NTFS file system by using the convert c: /fs:ntfs command, the conversion may not succeed. Even though the hard disk has several GB of free space you may receive the following error message:
The type of the file system is FAT32.
Determining disk space required for file system conversion...
Insufficient disk space for conversion
The conversion failed.
C: was not converted to ntfs
