Right now it does DD mode. If you don't want it to fail, it should write a disklabel (not a MBR). (If this is a non-boot disk in a FreeBSD only system this would be ok.) -- John Baldwin <jhb@FreeBSD.org> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
