A brief manual on how to use ddrescue
Download and burn Ubuntu rescue remix
List the available devices, partitions and file systems
sudo fdisk –l
Change current folder to /mnt. Note that you could mount anywhere but traditionally, mounts are done under this folder.
cd /mnt
Create a subfolder under which the USB drive will be mounted. This USB drive will be used to save the hard disk image. Note that you should use sudo in order to issue the commands as admin.
sudo mkdir folder1
Mount the USB drive on the newly created folder. Use the correct file system (ntfs or vfat for FAT32). Get the correct partition name and number from fdisk -l
mount -t ntfs /dev/sdxn /mnt/folder1
Start ddrescue to make an image of the partition into a file called disk.img (you can select any other file name). logfile is used to log the progress. Again, it can be any file name. This will do a first pass on the partition skipping the failed sectors.
ddrescue /dev/sdxn /mnt/folder1/disk.img logfile
Reissue the same command specifying -r 3 to retry the failed sectors three times. You can select a different number of retries.
ddrescue -r 3 /dev/sdxn /mnt/folder1/disk.img logfile
At this point you can reissue the previous command varying the number of retries to attempt further recovery of sectors that have failed so far.
To access the recovered data, you can either mount the image on a Linux system or copy the disk image into a new hard drive. To mount the image, first create a new mount point (an empty folder under /mnt)
sudo mkdir /mnt/folder2
Mount the image using the loop device that makes the disk image appears as a physical disk
mount -o loop –t ntfs /mnt/folder/disk.img /mnt/folder2
The data can now be accessed by getting into /mnt/folder2 either through the command line or the GUI
To copy the data into a new partition, issue the following command
dd if=/mnt/folder1/disk.img of=/dev/sdxn
where /dev/sdxn refers to the target partition on the new hard drive. Note that this partition should have been created with the exact same size as the original partition. A greater partition than the original would be wasting disk space. Once this is done you can boot Windows and run chkdsk to fix any file system error.
Warning: Issuing dd command with the wrong parameters can destroy your data. Make sure you specify the correct target device after /of=.
EX: # ddrescue -v -r3 /dev/sdc /dev/sdd ddrlog.txt [Source ] [ Destination ] [ logfile for continuity after failure]

OPTIONALLY: If you encounter a crash, you can clone from the back of the drive retrying all of the troubled areas from the back of the disk
# ddrescue -v -R -n /dev/sdc /dev/sdd ddrlog.txt
# ddrescue -v -R -r1 /dev/sdc /dev/sdd ddrlog.txt
This program will not recover the same sector twice (if its already been recovered and logged) because of the way it keeps the log file, so it will not be a waste of time to just repeat the same forward commands over and over if you experience crashes - however it doesnt hurt to just run a reverse command.

Ddrescue is software tool used for data recovery. Ddrescue will copy data from one device such as a hard drive or cdrom, to another device (internal or external) and tries to rescue data in case of read errors. It is available as a stand-alone bootable cd or as part of a multi-boot/recovery distro package such as SystemRescueCd.

Linux Ddrescue

GNU ddrescue is a data recovery tool. It copies data from one file or block device (hard disc, cdrom, etc) to another, trying hard to rescue data in case of read errors.Ddrescuelog is a tool that manipulates ddrescue logfiles, shows logfile contents, converts logfiles to/from other formats, compares logfiles, tests rescue status, and can delete a logfile if the rescue is done. Ddrescuelog operations can be restricted to one or several parts of the logfile if the domain setting options are used.The basic operation of ddrescue is fully automatic. That is, you don't have to wait for an error, stop the program, read the log, run it in reverse mode, etc.
If you use the logfile feature of ddrescue, the data is rescued very efficiently, (only the needed blocks are read). Also you can interrupt the rescue at any time and resume it later at the same point.

Ddrescue does not write zeros to the output when it finds bad sectors in the input, and does not truncate the output file if not asked to. So, every time you run it on the same output file, it tries to fill in the gaps without wiping out the data already rescued.

Automatic merging of backups: If you have two or more damaged copies of a file, cdrom, etc, and run ddrescue on all of them, one at a time, with the same output file, you will probably obtain a complete and error-free file. This is so because the probability of having the same area damaged in all copies is low. Using the logfile, only the needed blocks are read from the second and successive copies.

A python script to make it easier to use ddrescue. It provides a simple graphical method for using ddrescue. This is desgined to be as user-friendly as possible so users new to linux can use ddrescue easily. Age of empires gold edition mac download.

Simple GUI written in Python 2 designed to make the data recovery tool, ddrescue, easier for beginners to use. It also attempts to provide a user interface for everyone to use. It's designed for Linux, as KDiskRescue appears to be abandoned, with the last update in 2006. Also, DDRescue-GUI is desgined to look native on almost all Desktop Environments, though it may not on KDE. Note that this uses gddrescue, not the outdated dd_rescue. It uses very little rescources, with the current version using about 38MB RAM, and <80MHz CPU power, so it'll run on almost any system. The latest version of this program introduces loads of new features, and will now also run on Mac OS X 10.6 or later. For the OS X package, everything is bundled with DDRescue-GUI, including ddrescue, so there are no system requirements outside of the default OS X installation.Install DDRescue-GUI in ubuntu
