This is not to discourage from converting to NTFS. If you want to take
advantage of the security features in XP, you should convert to NTFS.
What you should know before you convert:
1.You cannot revert back to FAT without using third-party software. Windows
XP does not provide the tools for switching back from NTFS to FAT.
2.You cannot uninstall Windows XP and revert to a previous Operating System
after conversion. The conversion process will remove the previous OS backup.
3.In Multiple booting situations, only Windows XP, Windows 2000, and Windows
NT 4.0 (with Service Pack 4) can access NTFS volumes. If the computer has
Windows 95, 98, Me and Windows XP, you must use FAT on any partition that
Windows 95, 98 or Me must access.
4.Back up your data before conversion.
