Write file cache OFF

How can I disable the write cache file?

I need to write the file without cache ram.

Hmm...

Remount partition with -o sync option

or

write with O_DIRECT flag (if you know what is it)

You cannot turn off cache for one file, actually, only for the whole mount point.

// Why do you need this?

Oh, and as for drive caching - use "busybox hdparm -W 0 /dev/your_drive"
