Go to management menu = and look at "controller settings" and there will be the values of write cac= he=20 > and queuing and storsav. Make sure the values set there, are the same on= Linux and FreeBSD. You can download the LINUX version from 3ware's websit= e. Thank you very much, I've made it worked. In both FreeBSD and Linux the wri= te cache seems to be turned on in the web-based management. However, I stil= l don't think this is OS-specific, since I see no OS-specific options, and = 3ware makes the devices available through SCSI, and WC is handled different= ly there.
