If you are interested in accessing NTFS drives from Windows 95 or Windows 98 you should use NTFS for Windows 98 rather than NTFSDOS Professional, which is available as part of Winternals Administrator's Pak. If you want to salvage files off a corrupt NTFS volume or repair an NTFS boot sector or partition table, see Winternals' Disk Commander, also part of the Administrator's Pak NTFSDOS Professional mounts your NTFS volumes and gives them drive letters, so you can run applications and use files on NTFS volumes transparently. NTFSDOS Professional is small enough to run from a MS-DOS boot diskette so you can even access NTFS volumes on a system where Windows NT/2000/XP isn¡¯t installed or able to boot. This makes it ideal for repairing corrupt files or configuration problems that prevent a Windows NT/2000/XP system from booting. The advantage NTFSDOS Professional has over NTFSDOS is that it relies on Microsoft's implementation of NTFS rather than our own information on the NTFS file-system layout. However, NTFSDOS is still sometimes useful for cases where you want to recover data off of a NTFS drive that Windows NT/2K no longer recognizes, because NTFSDOS is more lax about recognizing NTFS drives than the Windows NT/2K NTFS driver. NTFSDOS Professional also comes with NTFSCHK, a tool for running the Windows NT/2000/XP CHKDSK program from within MS-DOS. NTFSCHK allows you to verify and repair the NTFS disk structure in case of accidental corruption. NTFSDOS Professional runs on MS-DOS and mounts NTFS drives so your MS-DOS applications can use them. It takes the files and drivers that compose NTFS from an existing Windows NT/2000/XP installation and simulates the environment they normally run in, allowing them to run inside of MS-DOS. This approach allows NTFSDOS Professional to access your NTFS volumes using the same Microsoft drivers that Windows NT/2000/XP uses, ensuring compatibility with your NTFS drives regardless of the version and Service Pack of NT you happen to use. NTFSDOS Professional is a 32-bit program which uses the DOS Protected Mode Interface (DPMI) to let it run in the 16-bit MS-DOS environment. It implements a network file system redirector, allowing the programs on your system to think they are making requests to a network drive, when in fact the requests are being routed to the NTFS file system driver and then to your local hard disk. Once you have run Creator you are ready to boot into MS-DOS and begin using NTFSDOS Professional. To start NTFSDOS Professional, simply execute it from the DOS command line or from your AUTOEXEC.BAT. NTFSDOS must be started from the directory that contains its support files. When NTFSDOS Professional starts it will scan all hard-disk partitions on your system looking for NTFS drives. It will mount each NTFS drive it finds with a unique DOS drive letter.
