bdflush() is a system call, not a program. See the bdflush man page, and /usr/src/linux/fs/buffer.c. I thought bdflush() only wrote dirty file system buffers, so another process (or kernel task) must be dirtying them. Try dropping into single-user mode ("telinit 1") and starting and stopping individualy programs (with "/etc/init.d/foo start" and "... stop") and seeing whether the disk is used. -- Carey Evans http://home.clear.net.nz/pages/c.evans/ GNU GPL: "The Source will be with you... always." -- TO UNSUBSCRIBE FROM THIS MAILING LIST: e-mail the word "unsubscribe" to [EMAIL PROTECTED] .
