    Hello,
    I am trying to disable write cache but it's not working.
    I have tried with several hard disks without success.
    I have tried with version is 5.3 and 6.1 but it still not working.

    Thanks in advance

      hdparm -W0

      That's how it's done, and it is permanent until overridden.

      But be wary of your system startup scripts -- they may include their own call to hdparm to turn it back on again (which is what most people really do want).

      Cheers
