well, you could surely achieve this by creating a copy of the (unmounted!) file system instead of the content therein. E.g. with dd [1], you need the arguments: if=/dev/sdc source device (disk or partition) with the file system to copy of=/dev/sdd destination device to be (over-)written iflag=fullblock a MUST to avoid effects of 'short reads' conv=noerror,sync continue on read errors, pad those with NULs bs=32M faster than using the default block size status=progress get some periodical status on the terminal $ dd \ if=/dev/sdc \ of=/dev/sdd \ iflag=fullblock \ conv=noerror,sync \ bs=32M \ status=progress [1] https://www.gnu.org/software/coreutils/dd Have a nice day, Berny -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
