Moi j'ai déjà travaille en écriture sur NTFS et j'ai jamais eu de problème avec.  
En théorie, l'écriture sur NTFS n'est pas fiable à 100 %, mais perso j'ai jamais eu de problème avec.  

[nom]La Documentation du noyau 2.4.19 a dit :[/nom]
To mount an NTFS volume, use the filesystem type 'ntfs'. The driver
currently works only in read-only mode, with no fault-tolerance supported.
 
If you enable the dangerous(!) write support, make sure you can recover
from a complete loss of data. Also, download the Linux-NTFS project
distribution from Sourceforge at http://sourceforge.net/projects/linux-ntfs/
and always run the included ntfsfix utility after performing a write to an
NTFS partition from Linux to fix some of the damage done by the Linux NTFS
driver and to schedule an automatic chkdsk when Windows reboots. You should
run ntfsfix _after_ unmounting the partition in Linux but _before_ rebooting
into Windows. During the next reboot into Windows, chkdsk will be run
automatically fixing the remaining damage. If no errors are found it is a
good indication that the driver + ntfsfix together worked to full
satisfaction. (-;
 
Please note that the experimental write support is limited to Windows NT4 and
earlier versions at the moment.
 
If you think you have discovered a bug please have look at the "Known bugs"
section below to see whether it isn't known already.
 
For ftdisk support, limited success was reported with volume sets on top of
the md driver, although mirror and stripe sets should work as well - if the
md driver can be talked into using the same layout as Windows NT. However,
using the md driver will fail if any of your NTFS partitions have an odd
number of sectors.
