I have disabled the write cache directly on the disk with IBM's feature
tool. The bad thing is that after a reboot, write cache is enabled again
which means that this drive doesn't store caching config permanently!

So I have put EXTRA_PARAMS=-W0 into /etc/sysconfig/harddisks and
rebooted. syslog confirms that:

[root@gw-linux-dev xinetd.d]# grep hdparm /var/log/messages
Mar 19 16:14:30 gw-linux-dev hdparm: /dev/hda:
Mar 19 16:14:30 gw-linux-dev hdparm:  setting drive write-caching to 0
(off)
Mar 19 16:14:30 gw-linux-dev hdparm: /dev/hdb:
Mar 19 16:14:30 gw-linux-dev hdparm:  setting drive write-caching to 0
(off)

So I should be safe. Tried a bonnie and the result shows that cache IS
off.

Tried

[root@gw-linux-dev xinetd.d]# ntsysv ; reboot

and got zeroed files in /etc/xinetd.d/ again!!!

What can I do now?
