View Full Version : [ubuntu] Disable write cache

How do I disable write cache on a disk?

Answering my own question:

A script has to be made in /etc/init.d that contains:
hdparm -W0 /dev/hdx[x]And then a link to it has to be created in /etc/rc.d with name SxxOriginalName. xx is from 00 to 99, lower means it will be executed earlier.

I have noticed that this method does not always work, maybe it worked just the first time but now the cache is on again.

Could you please help me?
