ncpfs does not support files bigger than 4GB.  If you get truncated 
files, I guess that your app is at fault, it should get SIGXFSZ or an 
error when you go over 4GB boundary:

(from fs/ncpfs/inode.c)

         sb->s_flags |= MS_NODIRATIME;   /* probably even noatime */
         sb->s_maxbytes = 0xFFFFFFFFU;
         sb->s_blocksize = 1024; /* Eh...  Is this correct? */
