Converting to NTFS
Although there are certainly third–party utilities that allow you to convert from FAT16 or FAT32 to NTFS (and may be cuter about it), you really don't need any special tool to perform the conversion—the necessary program is included on your hard disk as part of the Windows XP installation. To use this utility to convert your D drive, for example:
1. Close all open applications. This process may require a reboot, so be prepared.
2. Click Start, click Run, and then type cmd, and press Enter.
3. In the command windows, type:
convert D: /FS:NTFS
4. Press Enter.
That's it. If there are open files on the volume being converted, you'll have to reboot your system for the process to complete. And if this is a large drive that contains lots of files, the process could take a while to complete. I don't recommend that you try to do anything else while the conversion is occurring
