NTFS Changes in Vista. Any changes?

September 16th, 2005 by Jabez Gan [MVP]

Vista has Beta 1 and now there’s PDC build of 5219 available! Normal users will enjoy the new sleek UI (personal preference actually), with the Aero Glass Theme (the transparancy effect??).

For the developers, probably they are excited on how Vista is built and the under laying changes in Vista. Today let me talk about the changes of NTFS in Vista.

There are many changes to NTFS in Vista. For the “features” changes, here are a few:

1. The biggest change of all is the addition of complete transactional capabilities to NTFS. Transactional NTFS (TxF) allows all file operations on an NTFS file system volume to be performed transactionally. Read all about it on MSDN – http://msdn.microsoft.com/library/en-us/transact/fs/portal.asp

2. NTFS now has Symbolic Links. You can play with them using the mklink command in cmd. Read the CreateSymbolicLink documentation on MSDN – http://msdn.microsoft.com/library/default.asp?url=/library/en-us/fileio/fs/createsymboliclink.asp

3. NTFS has now “self-healing” capabilities”. In the past when you encountered a file-system corruption NTFS marked the volume dirty and CHKDSK was required to be run. In Vista NTFS will attempt to correct the corruption on-line without requiring a CHKDSK to be run. (Note- Not all corruptions will be fixed in the Vista timeframe and so in some cases CHKDSK will still be required)

4. The NLS casing table has been updated so that partitions formatted with Vista and Longhorn Server will both be able to see the proper behavior for the 100+ mappings that have been added to Unicode
but were not added to Windows.

A minor feature, unless your native language uses one of the characters that was not being mapped, an awful situation on a case insensitive file system!

Beta 2 will probably bring more changes to the NTFS foundation.

    So this is NTFS…Does this apply to winfs or is that not avaliable at present?

    What what what Self healing??? I hate CHKDSK wanting to run at bootup.. its only happened to me though when my machine has lost power and did a cold reboot when it was running.. Now… if only they’ll update defrag :-\

  3. Jabez Gan Says:

    Once I powered off on Vista and no CHKDSK… That’s because of this “self healing” thingy. :)

  4. Jerome Says:

    No, if you pwoer down/up the system, it is the journal of the NTFS filesystem which replays incomplete transactions and drop the corrupted ones, self-healing is most likely for hardware corruption in the MFT and such which is unlikely for you to create those conditions.
