Hi, I have put hw.ata.wc=3D"0" to /boot/loader.conf on some of my machines. After booting, sysctl shows: # sysctl hw.ata.wc hw.ata.wc: 0 However, atacontrol shows different results: # atacontrol cap 0 0 ATA channel 0, Master, device ad0: ATA/ATAPI revision 4 device model SAMSUNG SV1022D Feature Support Enable Value Vendor write cache yes yes it reports that write cache is still ENABLED ? I wonder if the output is just wrong or the cache is still being used. If I perform an "atacontrol reinit" then atacontrol cap starts to report write cache as disabled. I would very much like to write cache to really be off, since I have some machines running at locations which tend to have power failures from time to time. =09Ari S.
