Winternals Software's NTFSDOS Professional 5.0 is another Best Utilities tool that clinched its spot with a landslide win, and it's appearing here for the second straight year. NTFSDOS Professional is a powerful tool with which you can repair corrupted files or configuration problems that prevent Windows Server 2003, Windows XP, Windows 2000, and Windows NT systems from booting.
The drawback of using NTFS for Windows system partitions is that doing so doesn't let you access the NTFS volume to repair problems from a boot disk. NTFSDOS Professional solves that problem by giving you access to NTFS drives from MS-DOS and letting you create a boot disk with which to boot Windows systems. The disk contains an MS-DOS environment in which you can easily mount NTFS drives that have drive letters and run DOS programs to read, write, repair, or otherwise modify the drives, just as you would on FAT drives. You can also run third-party applications to effect a wider range of repairs.
