Should do it. Check the dd syntax for yourself, of course, and always work on a copy. Should be instant if your output file is on a filesystem that supports sparse files. You should be able to do the same with ddrescue: you want to skip 320GB of your output file and write 1 block of zeros. _______________________________________________ Bug-ddrescue mailing list [email protected] https://lists.gnu.org/mailman/listinfo/bug-ddrescue
