r 3 menas it will go over unrecoverable sectors 3 times before giving up. Once this is done, we runĭdrescue -f -d -r 3 /dev/sda /dev/sdc logfile.log If the drive is in poor shape, we want to grab the easy parts first. This command copies everything over from /dev/sda(our source drive) to /dev/sdc(our target drive), while skipping content that can't copy faster than 5 megabytes per second. Now, we type the following command: ddrescue -f -n -a 5120000 /dev/sda /dev/sdc logfile.log Using ddrescue to make a block-for-block copy of the bad source drive. dev/sdc just showed up, so we know that is our target. # fdisk -l | grep dev WARNING: fdisk GPT support is currently new, and therefore in an experimental phase. Do note all data on the external will be written over, so ANY DATA on the external MUST be backed up or it will be GONE! Now, we move onto plugging in our blank external. If you have the bad drive in your machine that you would like to recover, you now know it is /dev/sda. If you have a machine with one internal drive, and that is the drive you are looking to recover, the drive you see here will be our source.

You can differentiate the systemrescuecd drive as it will be much smaller, the size of your USB drive that you used for systemrescuecd. You should see one for the drive in your system – here, ours is a 500 GB drive, and then another for systemrescuecd. Use at your own discretion.ĭisk /dev/sda: 500.1 GB, 500107862016 bytes, 976773168 sectorsįdisk -l will show us a list of all drives. WARNING: fdisk GPT support is currently new, and therefore in an experimental phase. We need to figure out which drive is the source and which drive is the target – there is no undo here, so proceed with caution!įirst, we type this command # fdisk -l | grep dev Linux names drives in this fashion: /dev/sda, /dev/sdb, /dev/sdc, etc. Many systems may also show you the actual brand/model of the USB drive, rather than the name of the operating system at this point. Choose the systemrescuecd liveusb you made. Most machines allow you to choose what drive you boot up into using F12 or F11 – on Macs, holding down the option key is how this would be done. Once you’ve created a systemrescuecd live USB, you will have to reboot your computer into the operating system.

In order to try and carry out a data recovery yourself, you will need systemrescuecd, a bootable Linux livecd/liveUSB that includes the tool ddrescue, a USB drive to install it to, and another hard drive connected via USB so that you can clone the faulty drive to it. With a tool like DDRescue, it is possible to recover and clone parts of your data. However, for cases where there is minor damage or just bad sectors, it may be recoverable on your own. In those cases, you will likely need a professional. A crashed hard drive can be the results of broken heads, or just bad firmware.
