But it doesn't "touch it" so ZFS continues to work if you enable write caching. And I think we default to "write-cache" enabled for ATA/IDE disks. (The reason is that they're shipped with write cache enabled and that's the only setting tested by the manufacturer) Casper _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
