[Linux-NTFS-Dev] Linux LDM v0.0.5 (Windows Dynamic Disks)

[Richard R. <nt...@fl...>]

Hi All,

I've just released 0.0.5 of the LDM code.
It can be downloaded from:

  http://linux-ntfs.sf.net

Briefly, the major changes are:

  It's much more efficient (the database is cached)
  Support for md autodetection
  A new tool (ldmutil) to tweak the LDM database
  Numerous bug-fixes

Most of the credit goes to Jakob Kemi who's been doing
a marvellous job (though it took a while for me to understand
/what/ he's been doing :-).

Any questions or comments, please email me.

Cheers,
  FlatCap (Rich)

Re: [Linux-NTFS-Dev] NTFS Wirte?

[Richard R. <nt...@fl...>]

Hi Martin,

> So for me NTFS is useless till we can do write with it.

Unfortunately, this is the case for some people.
For others read-only support is useful enough.

> When is it planned?

This is a difficult question.  Read support is inherently easy.
You give the user anything you can understand.

Writing, however, is very difficult.  NTFS is built like a database.
Every piece of information is stored in several places.  If you make
even a simple change you have to know where to write the info.

For example when you rename a file, the name is stored in the MFT
(a large table).  It is also stored in indexes (directories) which
are kept in alphabetical order.  The indexes are kept in a balanced
b+ (binary) tree.  If you change its position then you may need to
rebalance the whole tree.  This is non-trivial.

This means that even the simplest _write_ operations quickly become
very difficult.

Answering your question: only easy bits of writing are supported.
This will change when Anton has time to code it (this is only his hobby)
or we get more help (hint :-).

> Read-only... Maybe that's why it's not in RedHat kernel.

Possibly, but rumours hint at another reason.

[Linux-NTFS-Dev] CFT: NTFS TNG 0.0.2

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

Hi all,

NTFS TNG 0.0.2 release is now available in CVS, module ntfs-driver-tng, 
branch tng-0-0-2. (to check it out use: cvs update -r tng-0-0-2 in your 
ntfs-driver-tng local repository/directory which you can obtain as per 
instructions on the linux-ntfs.sf.net website, then apply the patch in the 
patches directory to your running kernel, recompile and install new kernel 
then compile the ntfs module, install it, and your are all go).

The driver now supports compressed files/directories as well as attribute 
lists (but not yet attribute extents) thus it will work on medium sized 
volumes.

It survives happily the test
         find . -type f -exec md5sum "{}" \;
on my 1.1GiB test partition with over 16k files on it, many of which are 
compressed files/directories.

Please test and report any problems/bugs back to the list. Thanks!

Note that gcc-2.96/3.x or later is required to compile this driver.

Best regards,

         Anton

[Linux-NTFS-Dev] NTFS Wirte?

[Martin P. <mpi...@os...>]

So for me NTFS is useless till we can do write with it.  When is it planned?

Maybe that's why it's not in RedHat kernel.

Thank you.

[Linux-NTFS-Dev] NTFS HOWTO

[Linux-NTFS-Dev] NTFS HOWTO

[Richard R. <nt...@fl...>]

Hi All,

I finally got around to writing (starting to write) an NTFS HOWTO.
It's basic and incomplete, but it's a start.

It covers three areas so far:

  NTFS Technical questions

    These are only really technical to novices.  There's a set
    of general NTFS questions I haven't yet typed up.  It covers
    how to deal with NTFS as a Win 95/98/ME user.  It makes NO
    reference to Linux.

  How to build the Linux NTFS module

    This refers to a LOT of other sources and should be enough
    for a keen Linux newbie to add NTFS support.

  How to mount an NTFS partition

    More newbie tips on mounting.

I doubt any of this will be new to you all, but it should save me
time answering all the newbie mail I get :-)

Any suggestions, let me know.

Cheers,
    FlatCap (Rich)

Re: [Linux-NTFS-Dev] NTFS module with 2.4.9 kernel?

[Richard R. <nt...@fl...>]

Hi Martin,

Of course, if I wasn't such a [expletive deleted] I'd have told
you where to find the HOWTO I've written :-)

Re: [Linux-NTFS-Dev] NTFS module with 2.4.9 kernel?

[Richard R. <nt...@fl...>]

Hi Martin,

> I'm new to it but can't find howto do the module for my 2.4.9-12
> RH 7.1 kernel.

Unfortunately RedHat don't distribute NTFS support.  I don't know why
not.  However they do suppy the kernel source and a .config file which
simplifies building your own kernel.

I've just finished the first draft of an NTFS HOWTO (which mostly points
at other HOWTOs :-), which explains what to do.

Let me know if you have any problems / questions.
