Hello, I need to duplicate a huge number of identical 8GB SD cards on which I have 1GB of data at the beginning of the disk on various partitions and then a 7GB ext3 partition which is rather empty (just a few MB of data). The duplicator device enables me to select which sectors I can binary-duplicate. I would love to divide by 8 my duplication time, by duplicating only the first GB and then the beginning of the 7GB ext3 partition. When I do a mkfs.ext3, I see that the super-block is written to various locations of the partition which is not good for the optimization I would like to do. Anyone can advise how I could optimize my duplication? What are my options? Would it be the same situation for ext2? Meaning where is the journal written on the ext3 partition? Is there a single version or multiple versions? Thanks in advance for any answer or pointer, Gregoire _______________________________________________ Ext3-users mailing list Ext3-users@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/ext3-users
