ddrescue

Ddrescue is a pretty handy tool when it comes to recovering lost data. If you need to install and run it, here’s a simple guide to get you started!

How to Install ddrescue

First off, you’ll need to unarchive the files. Then, open up a Terminal window on your Mac or Linux system. From there, navigate to the folder where ddrescue is located. You can use these commands:

.\/configure

  make

  sudo make install

  ddrescue

  

Automatic Operation

The best part about ddrescue? It runs fully automatic! That means you don’t have to wait around for an error or stop the program just to read a log file. It handles everything for you!

Efficient Data Rescue

If you turn on the logfile feature while using ddrescue, it becomes super efficient at rescuing your data. Only the blocks that are needed get read, which saves time and effort. Plus, if you need to take a break or something goes wrong, you can stop and then resume right where you left off.

Merging Backups Automatically

If you've got multiple damaged copies of a CD-ROM or file, ddrescue can work wonders! Just run it one at a time with the same output file, and you'll likely end up with a complete and error-free copy. Why? Because it's rare that two damaged files will have issues in exactly the same spots.

Crash Recovery Made Easy

Your logfile is saved periodically on disk, which means if your computer crashes during recovery, you can quickly pick up where things left off without having to redo too much work.

Using Logfiles Effectively

You can even use the same logfile for different commands that focus on various parts of your file. This is super handy if you're attempting recovery multiple times across different sections.

I/O Buffer Alignment

Ddrescue aligns its I/O buffer with sector sizes so it works smoothly with raw devices. For extra efficiency, it also aligns with memory page sizes whenever possible.
