Still have good quality older sata hardware raid cards that require 512 bytes/sector. As far as I know HD manufacturers are not making native 512 bytes/sector drives any more. Some have better 512e emulation than others. Looking for some advice on which to avoid and which are recommended. Thanks. PS this is for a CentOS6 server. _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos
