CBD(Copy Bad Disk) can copy files regardless of bad sectors. CBD skips the bad sectors and continue to copy the rest content of the file so it will not hang, freeze or fail. With well-designed algorithms, CBD can recover files and salvage as much data as possible from hard drives with bad sectors. During the copying process, you can choose to skip the current file or speed up by allowing CBD to ignore more sectors after encountering a bad sector. CBD generates a log file recording the positions of unreadable bytes of the copied file so that you can repair the damaged file using other software. Those unreadable bytes are replaced with 0s in the destination file. As integrated in the context menu of Windows Explorer, using CBD is like ordinary file copying/pasting operations with the difference that you need to choose the "Paste Bad File" option instead of the "Paste" option when right-clicking in the destination folder. To back up a whole HDD with bad sectors, just select/copy all files on it.
