	        Mark4NTFS for Windows NT/2000
	        -----------------------------

Short description:
------------------
 The programm Mark4NTFS can mark NTFS filesystems as 'NTFS 4' 
 (or 'NTFS 5'/Windows 2000) to enable disk checking in NT4 after 
 installation of Windows 2000.


some details:
-------------
 Windows 2000 converts a filesystem from 'NTFS 4' to 'NTFS 5' 
 every time it starts.

 You need at least SP4 to allow partial access to 'NTFS 5' disks in NT4. 

 To have full control over NTFS disks in NT 4 (functional repair tools 
 after an unsafe shutdown) the filesystem must be of type 'NTFS 4' 
 otherwise CHKDSK will not work and reports:
 ---------------------------------------------------------------------------
  This NTFS volume was created or modified by a later version of Windows NT.
  This version of chkdsk cannot be run on this volume.
  You must boot the version of NT that created/modified this volume and run
  chkdsk from that installation.
 ---------------------------------------------------------------------------


useage of Mark4NTFS:
--------------------
 Mark4NTFS  [command/options]  X:
            where X: should be the name fo the NTFS drive

 commands: 

  Mark4NTFS -NTFS4 X:     try to mark as NTFS4 filesystem
  Mark4NTFS -NTFS5 X:     try to mark as NTFS5 filesystem

  Mark4NTFS -b<file> X:   make backup of $MFT and $MFTmirr record
  Mark4NTFS -r<file> X:   restore the $MFT and $MFTmirr from the file

 options:                (rarely used to show/dump some MFT infos)
            -v            show drive infos
            -c[<123>]     show all/selected cluster info
            -f[<123>]     show all/selected file record/sector info
            -a[<123>]     show all/selected attribut info
            -<456>        set debug flag (sample: -777)


After applying a mode change you have to execute a disk error check 
programm ("CHKDSK.EXE") to remove garbage from the previous mode.\n

after changing the type:
------------------------
 When you call CHKDSK after changing the mode from NTFS 5 to NTFS 4 you 
 will get some error messages which should look like the following:

-------------------------------------------------------------------------
C:WINNT> CHKDSK /R X:

The type of the file system is NTFS.

When changing from 'NTFS 4' to 'NTFS 5' in Windows 2000 the system has 
to modify/repair the NTFS disk too.
