It depends on the drive. According to Anandtech, the WD drives use 4k internally but report 512b sectors. They also report that the Seagate GoFlex uses 512b sectors internally but reports 4k sectors through it's desktop dock. So the WD drives should work, and the Seagate drive should work but both of them lie about their abilities. Waiting for a 3TB drive that properly reports it capabilities to become available is probably the best course of action. -B -- Brandon High : bh...@freaks.com _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
