HELP ! ! My hard disk is Read-Only now !

[Alexander]

I boot my computer with live CD , but I can't configure SCIM , so I have to type in English.

I use sysv-rc-conf as "Speed up ubuntu boot process" says, and add "hdparm" to S runlevel (it was not in any runlevel before).
After I reboot, many error messages had showed on screen and it took very long time before gdm appears. Then I found each filesystem of my hard disk was read-only.

Now I can mount my hard disk by live CD, please tell how to remove "hdparm" from S runlevel?

MANY THANKS!!!
