I've got an external eSATA enclosure as well which is using a Silicon
Image Chipset and its connected to a Silicon Image SATA controller just
like yours. So far, I haven't figured out how to turn off the write
cache. I even tried playing with it on Windows (both XP & Vista) and so
far, there is no way to disable it. This seems like a common problem
with Silicon Image Chipset + Silicon Image SATA controller. There's a
lot of complains on google about this but no fixes that work.
If anyone on the list has any first hand experience in resolving this,
I'm all ears.

Hi. atacontrol is reporting that the write cache on an eSATA enclosure I
am using (Silicon Image chipset) with Silicon Image SATA controller has
write cache enabled even though I want it disabled in loader.conf. My
feeling is this has to be controlled by the enclosure, though such
control doesn't exist. Is this it, or is the OS still responsible for
turning off cache on external drives? What's your experience? Thanks.
