The "wisdom" I have gathered is not to use dd for such disk duplication, but to use fdisk for partitioning, and "rsync -ax /orginal/ /target/" for file copy (be careful with the trailing /'s). The first reason is that dd copies bad blocks, and the second reason is that rsync over a blanck partition defrags the files. A second rsync allows to check fast the first copy. The third argument is that often disks are not strictly equal, and then dd is anyway not recommended. Some use tar instead of rsync. Dan
