upd: The case is that needed_partition boot_sector became BAD or seems so. I need to clone the whole disk with disabled partition table. If the table is disabled, OS will NOT try to read the boot sectors of the partitions and will not see any partitions, so further copying of /dev/sdb2 becomes impossible!!! What is the best solution? The disk_being_copied seems going to die very soon :(. It must be used the minimal possible time, with no tries to read any bad sectors! _______________________________________________ Bug-ddrescue mailing list Bug-ddrescue@gnu.org https://lists.gnu.org/mailman/listinfo/bug-ddrescue
