Convert FAT to NTFS
Click Start, click Programs, and then click Command Prompt. In Windows XP, click Start, click Run, type cmd and then click OK.
At the command prompt, type CONVERT [driveletter]: /FS:NTFS. Convert.exe will attempt to convert the partition to NTFS.
NOTE:
Although the chance of corruption or data loss during the
conversion from FAT to NTFS is minimal, it is best to perform
a full backup of the data on the drive that it is to be converted
prior to executing the convert command.
