Samba WRITEX packet with 32k and only with response

[MAAOUI.Wael]

It seems to be Vista client
This is a bigger capture

http://www.nabble.com/file/p23977234/FAT32_WriteX.rar FAT32_WriteX.rar 
But what's strange with a this  capture is the 32768 bytes transferred, i
always obtain a WriteX packet with 64ko and with an alternation between
request and response.
So the question is how can we obtain a WriteX with 32768.

thanx
