Also copying process from faulty source should be iterative, starting with full image copy using big block size and then trying to retry copying bad block using 512 bytes size. Using specialized tools like dd_rescue are also of a big help. I had one case when I had been facing faulty harddrive that had been returning garbage data when trying to read bad sectors instead of reporting the system about unreadable block. Key point to dig the data from it was to create ~20 copies of disk image from it and then use statistical methods to determine which data for each sectors to use. -- Best regards, Alexey Loukianov mailto:mooroon2@mail.ru System Engineer, Mob.:+7(926)218-1320 *nix Specialist
