Write cache

Because I've lost a lot of data using postgresql (and I know for sure this
should'nt happen) I've gone a bit further reading documentations on my
disks and...

I have FUJITSU MAP3367NC 36G 10000 rpm disks, those disk have a write
cache of 8Mb, if someone could tell me hox to turn it off... Could'nt find
it in the docs and this could very well explain why a busy database
crashes every time

Thanks for your help
