libata and write cache

I am just wondering how to enable write back caching with libata.

dmesg gives me

SCSI device sda: drive cache: write through

I would like to use the drive's wirte caching feature to improve performance /I know it is a bit dangerous with a flaky system).

Could anyeone tell me how to do it?
