status of ntfs write-support in 2.4.20

Hi,

What is the status of NTFS WRITE(!)-support in 2.4.20?
Is there any kernel which can do safely writing to windows nt(! not 2000
or xp) partitions?

I believe it is still very unsafe. It *can* be done but you have to mess with
scandisk everytime you reboot back to windows...it's very very dirty and quite
hackish. I wouldn't think about risking data on an NTFS partition through the
limited NTFS driver in Linux 2.4 (even 2.5.)

And windows NT/2000/XP partitions are all the same NTFS anyway.

Regards
Josh

Well, the ntfs driver from the 2.4.20 vanilla kernel has really dangerous
write support for the ntfs partitions. It is strongly discouraged to use
it.

You can use though the backport driver from the 2.5 kernel series (aka
ntfs-tng). It allows you to overwrite the files using mmap() and write().
So, neither size changes, nor attribute changes. You'll find mode detailes
along with the driver itself at http://linux-ntfs.sf.net/.

Not really. See http://linux-ntfs.sourceforge.net/info/ntfs.html#1.4

1. IBM x440 problems on 2.4.20 to 2.4.20-rc1-ac3

Helo,
I'm trying to boot from linux kernel 2.4 tree
i've installed rh 7.1 dist, but system seems only 3 procesors, so i made
2.4.20 kernel with smp without NUMA support and i saw 4 processors. Next
2.4.20 with numa support, and system hangs on mounting root filesystem (no
scsi devices found, ide devices lost interruption, no keyboard found etc
etc)
Next 2.4.21-rc1-ac3 without NUMA, 3-processors available
with NUMA support and summit/exa support and clustered apic support kernel
boots, found scsi devices but hangs on it with lost interruption, also with
ide devices and so on
machine has 4 HT processors and 8GB of RAM
any ideas or help?

i don't wat to use 2.5.x kernel.....

regards

Sobczak Wojciech
