When will this be supported in libata. I have drives attached to a
AHCI controller and want to turn drive write cache OFF. Sdparm will
not allow me to do so. Any work-arounds or patches would be greatly
appreciated. I am also using kernel 2.6.18.

Thanks

Don

hdparm -W0 /dev/sda

It works just fine.

Cheers

Thanks,  It worked just fine like you said. I thought I could only use
sdparm since these were SATA disks.
