Hi,

This is my configuration. I have XP running on a
system which has 2 disk with software RAID 0.

Yes, there is already an almost complete read-write driver [willing to beta
test? ;)] but it runs only on NetBSD, not yet Linux. The reason, NetBSD was
the development platform is that, it's the only non-Microsoft OS that have
been ported to the hardware architecture needed to satisfy Longhorn
resource requirements.

OK, that was the joke part :)

It's still a hype, for about 10 years? The latest leaked version of
Longhorn doesn't use WinFS as the native file system, well actually it's
not even available. WinFS is told to be based/derived from MS SQL Server.

I think NTFS is still have about 10-15 years ahead.

I was :) I also enabled the "see private info" option.

Well, apparently I didn't screw anything however the announcements came a
bit strange like

	Linux NTFS 2.1.3a (NTFS TNG Driver 2.4 Backport)
	Linux NTFS 1.7.1 (NTFS Tools and Library)

instead of

	NTFS TNG Driver 2.4 Backport 2.1.3a
        NTFS Tools and Library 1.7.1  (or ntfsprogs 1.7.1)

I also tried to delete the 'NTFS TNG Driver' branch because that's for 2.5
and already included in the 2.5 kernels so it's outdated but couldn't find
any way to do so.

From what I remember you don't need anyone to give you access. You just do
it yourself. (Yes it does seem odd but it allows for unmaintained projects
to be taken over by someone else easily.)

They need to be all updated by hand and the freshmeat interface is a
little bit of a pain/very slow sometimes.  I had actually forgotten about
it...  Feel free to update it if you want.

It appeared now. However I also noticed no updates/announcements on
Freshmeat. Latest driver is 2.0.3 and ntfsprogs 1.7.0beta :-o I thought
these get updated automatically based on SourseForge changes and

Ahh, you mean you have _a lot of_ files ("quite a few" = lot), you wrote
you have "0 81816576 MFT entries" (I thought you just made a copy-paste or
whatever mistake, it didn't make any sense). If it's indeed almost 82
million MFT entries then I don't wonder. Usually people have 30-200
thousands. Rarely I've seen a couple of millions but never 82 millions. If
it's true then you might have found an ineffciency feature in the Windows
NTFS driver.

[Linux-NTFS-Dev] Re: peculiar MFT structure

[Anton A. <ai...@ca...>]

Hi,

[I am CC ing ntfs-dev]

Your answer is that you need to read our docs more carefully. In
particular you will find your mft record contains an $ATTRIBUTE_LIST
attribute which tells you where you can find further $MFT/$DATA attribute
extents and those will tell you where your mft records are located.

Because it's my term-task, and I need to do NTFS reading by myself.

It starts where 'Offset to the first Attribute' defines it in the FILE
record:

But why don't you use libntfs from ntfsprogs? You could progress much
faster.

- read-only, but with safe file overwrite support without changes
	  to the file size

        - read-only except for safe file overwrite support without changes
	  to the file size

You can take that part of the sentence out then... As I did above.

Unfortunately I'm not sure the 'change file size' feature fits the current
feature freeze :(

Otherwise of course it's ok, you must know it the best :)

Oops, I forgot to send the URL. Usually it's posted to linux-kernel and
some news sites (e.g. Linux Weekly News). Also available here:

    - stable
    - much faster
    - read-only except for safe file overwrite support without changes to
      the file size (a development version allows changes in file size
      already and it might be completed in time for 2.6 but no promises)

Above is my proposed updates. Otherwise good idea. I didn't know about
this list. Where is it?
