It requires sudo permissions because it can read, write, and destroy data!įortunately, I had another identical size external USB drive too, which I attached via USB. Now you can use the system key to find and run DDRescue-Gui - just type 'DDRescue' and load the app. $ sudo add-apt-repository ppa:hamishmb/myppa Then you can install and update in the usual way. The easiest way to install is to add the author's repository to your Ubuntu sources. If you interrupt the rescue and then reboot, any partially copied partitions should be hidden before allowing them to be touched by any operating system that tries to mount and "fix" the partitions it sees.ĭDRescue-GUI helps users recover important data fast, using GNU ddrescue but without having to understand the command line, which can be daunting.If you reboot, check the device names before restarting ddrescue. Some systems may change device names on reboot (e.g.If you use a device or a partition as destination, any data stored there will be overwritten. Never try to repair a file system on a drive with I/O errors you will probably lose even more data.It is best that the device or partition to be rescued is not mounted at all, not even read-only. Never try to rescue a r/w mounted partition.You need to understand what it does, and you need to understand some things about the machines it does those things to, in order to use it safely. GNU ddrescue is like any other power tool.This is why it can be helpful to have the DDRescue-GUI and optionally, GParted, to provide a better visual check before you might destroy the existing data on a destination drive!įrom the GNU ddrescue Manual, all emphasis mine! You should take care to remember that any data on a chosen destination will be replaced. In this case unmount the drive if you mounted it and try to recover an image of all you can onto a new good drive, ideally of the same capacity and form factor if it is destined to be a replacement for a broken computer. You should allow the tools you run to finish, avoid running them on mounted partitions and never try to repair data on suspected damaged drives. With any tool capable of erasing data, there is the opportunity to make a mistake that results in the source data being damaged. Please read this or risk losing your data! You probably came here because of a data recovery issue. Ubuntu 22.04 LTS shipped with release 1.23 which is a little behind the current release, but for LTS users I would recommend sticking with the release provided with the LTS distribution unless you absolutely know you need a fix made in the current release. As is often the case your distribution might be a little behind the upstream release. GNU ddrescue is an essential tool for data recovery originally released in 2004 and consistently updated by the original author. It copies data from one file or block device (hard disc, cdrom, etc) to another, trying to rescue the good parts first in case of read errors.
