You’re probably thinking it sounds like the venerable dd command, and it is similar, with some significant improvements. It performs block-level copies of the failing media, and so it doesn’t matter what filesystem is on the media. Fortunately, SystemRescue doesn’t mess with the original binary names, and calls them /usr/bin/ddrescue and /bin/dd_rescue.Įnough of that let’s talk about what makes GNU ddrescue my favorite. But the binary for gddrescue is /sbin/ddrescue, and the binary for dd_rescue is /bin/dd_rescue. The Debian package name for GNU ddrescue is gddrescue, and the package name for dd_rescue is ddrescue. Just to keep it interesting, Debian Linux adds its own bizarre naming conventions. dd_rescue is nice, but it’s slower than ddrescue and doesn’t include as many features.
There is also a dd_rescue, version 1.23, by Kurt Garloff. The version on the current SystemRescue release is ddrescue 1.14. GNU ddrescue, by Antonio Diaz, is the one I prefer. There are two ddrescue programs in SystemRescue. Before we dive into the fun stuff, there is some vexing naming confusion to clear up. GNU ddrescue is included in the default SystemRescue image. When a hard drive, CD/DVD, USB stick, or any digital storage media is on its way to the Great Bitbucket in the Sky, GNU ddrescue is my favorite data recovery tool. So run fdisk -l to see your block device names, and then run these commands using your own device names:īe very sure that you are doing this to the second partition on your USB stick, and not to your hard drive.

The SystemRescue manual says to always create subdirectories in /mnt, and never mount anything in /mnt itself. It does not automount any filesystems outside its own root filesystem, so you will have to mount the new partition manually. I use the excellent GParted for this, and formatting it as fat32 prevents file permissions headaches.

Then shrink the single partition and create a second partition in the free space.

Do not boot it up yet, but make sure it is plugged in to your PC and unmounted. But with a little work you can partition your SystemRescue USB.įirst create your SystemRescue USB. I like having a separate data partition, but usb_inst.sh overwrites the entire device, and there is no option to partition it. You can copy files to the /home directory on the SystemRescue USB and have an all-in-one rescue stick. You get root privileges by default, so this is a mighty power tool all ready to do real work. You can also have a nice XFCE desktop by typing wizard at the prompt. SystemRescue boots to a console by default. Just follow the prompts, and presto! Instant live SystemRescue USB. You can run this either in an X terminal or from the console. Plug in your USB stick, and if your system auto-mounts it then you need to unmount it. You need the exec option so you can run the USB creator script. Sudo mount -o loop,exec systemrescuecd-x86-2.3.1.iso temp/ After downloading the CD image, create a temporary directory and mount the image with the loopback device: All you need are a USB drive that holds at least 512 MB, and the latest SystemRescue CD image. The fine SystemRescue folks have made it easy to create a bootable SystemRescue USB stick by adding a script to the CD image that does all the work for you. This varies on different machines as motherboard manufacturers love to monkey with this stuff, so I’m afraid you’re on your own for finding out what your systems support. Then you get a menu for picking your boot device without having to enter the BIOS configuration. Just plug in your boot media, power up your machine, and then press the appropriate hotkey, which is usually an F key. Some BIOS have a really nice feature: a boot device picker. Any PC built after 2001 should have this capability, though the older ones don’t always work. The one roadblock with live USBs is your system BIOS must support booting from USB devices.
(Unless you use a CD/DVD-RW, but these are not always reliable.) A bootable SystemRescue USB stick is fast, and you can copy files to it. Live Linux CD/DVDs are easy and good, but they have two drawbacks: they are slow, and they are not writable.

Today we will learn how to create a SystemRescue live USB stick, and recover data from failing drives.

It can rescue Linux, Unix, Mac, and Windows systems, and recover data from almost any media. The Gentoo-based SystemRescue CD/USB is one of the very best rescue distros, packing amazing functionality into a 350MB image.
