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. -- Jacques Manukyan Dan wrote: > 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.

What's your experience?
