That's cool to know. I am developing a new NTFS driver - NTFS TNG. It is 
read-only for now and it is almost complete with regards to basic read 
support. I.e. it works NOW. - The only thing that is missing is attribute 
list attribute support but I am working on it as we speak. (-;

If you or anyone else of course is interested in participating in 
development, have a look. Code is in module ntfs-driver-tng in Sourceforge 
linux-ntfs CVS. URL with cvs access details:

         http://sourceforge.net/cvs/?group_id=13956

Note that the module requires some small changes to the core kernel and the 
appropriate patch is maintained in ntfs-driver-tng/patches directory. 
Currently kernel 2.4.15-pre4 is supported but patch might apply to later 
-pres as well.

After applying the patch and installing the new NTFS module sources NTFS 
TNG is completely separate from the kernel tree (all code including headers 
is in fs/ntfs and nowhere else and the include/linux/fs.h dependencies are 
gone).

One word of warning: NTFS TNG requires gcc-2.96 or later to compile. It 
will NOT compile with earlier versions of gcc! You will just get a million 
or so errors if you try any earlier gcc compiler...

Best regards,

Anton

I am not bothered about the journal until there is fully working support 
for NTFS on Linux. After that I will start thinking about journalling.

I haven't noticed any changes between Win2k and WinXP except for the 
extension of the MFT_RECORD structure (see 
ntfs-driver-tng:linux/fs/ntfs/layout.h) to contain the mft record number 
(great data recovery info). Although it is confusing that they are only 
using 32 bits there as otherwise the mft record numbers are 48-bit. Not 
quite sure what to make of that...

 From what I have read I doubt the DOJ settlement will be any benefit to 
NTFS development on Linux but it's certainly worth a try.

Best regards,

Anton

Anton,

Can you help this person?  My 18 months has now expired.  I can help 
on NTFS now if you need some help.

Hi,

sorry to bug you but I am in same serious trouble with W2k NTFS after bad memory crash trashing my disk with a year of video edited klips that I work with. Could you send me the tool to try fixing the problem with it, please?

Kind regards,
vojkan petkovic

Anton,

I will downlaod and review where the code is at.  Write support is
going to be very tough at this point -- they have changed some of 
the on-disk strucutures again for the journal and several meta 
files.  However, with the DOJ settlement, they will be required to 
share this information, so our job could get easier.  I will 
approach some folks and see where they are at.  Hopefully, it won't
go down the way it did last time.

Jeff

This is because you are not messing around with the journal at present.

I fired off an email to them.  The worst that can happen is they will 
say "Hell no."
