Writing to NTFS and kernel 2.6-test11

Writing to NTFS and kernel 2.6-test11

[pprice]

I have read that it is possible to change a file as long as it is the same
size using write(2) and mmap(2). I don't seem to be able to make this
work. I was wondering if someone has some code that will allow me to do
this. Any input would be greatly appreciated.

Thanks,
Paul

Did you compile in read-write support?

What is the message in syslog when NTFS loads? If it is a module then type
"modprobe ntfs" to make sure it is loaded.  If not a module or a module
and you have loaded it just type: dmesg | grep -i ntfs and please tell me
the output you get from that.

Also, note that writes to resident files are not permanent in the driver
in 2.6-test11 (i.e. small files about 500 bytes or so).  They are never
written to disk.  Bigger files >1kb are guaranteed to be written always.

Best regards,
