Nope it didnt work

here are the first lines of my /etc/inittab
-----------------------------------------------------------------------
# /etc/inittab: init(8) configuration.
# $Id: inittab,v 1.9 2001/05/31 10:37:50 knopper Exp $

# The default runlevel.
id:5:initdefault:

/sbin/hdparm -d 1 /dev/hdc

# Boot-time system configuration/initialization script.
# This is run first except when booting in emergency (-b) mode.
si::sysinit:/etc/init.d/rcS
-----------------------------------------------------------------------

Also on boot up I notice there is a message saying something that
line 7 in etc/inittab is too long only 4 characters are allowed.

Line 7 is the /sbin/hdparm -d 1 /dev/hdc command.

After I logged in I did /sbin/hdparm -d /dev/hdc

here are the results

luis@Sphinux:~$ /sbin/hdparm -d /dev/hdc

/dev/hdc:
using_dma = 0 (off)

but if I type in the command in root it makes the changes

any other ideas?
