You need to create the sdb2 partition with fdisk first. ddrescue -f -r3 /dev/sda /dev/sdb mapfileĮxample 2: Rescue an ext2 partition in /dev/sda2 to /dev/sdb2. dev/sdb beforehand, but if the partition table on /dev/sda isĭamaged, you'll need to recreate it somehow on /dev/sdb. You can probably work along the instructions of one of the examples.Įxample 1: Fully automatic rescue of a whole disc with two ext2

Please read it carefully before starting the work. When ddrescueis installed, there is a very good tutuorial at info ddrescue a slow step to clone the sectors, that are difficult to read, but may still be readable, if trying slowly and repeatedly.a quick step to clone the sectors, that are good (and easy to read).Which is a tool, that can clone in two steps, I suggest that you use `ddrescue', sudo add-apt-repository universe In order to do this, you'll need to create a partition on your target drive first. If at all possible, try to only recover the minimum amount of data necessary - a single partition, for example. You can access it with the following command: man ddrescueĪ full disk ddrescue is doable, but is somewhat frowned upon due to putting unnecessary stress on the disk.

We're going to use the -d option to read the disk directly, and the -r3 to retry a bad block three times before moving on. Once we have our names, we can just run ddrescue: sudo ddrescue -d -r3 /dev/sda /dev/sdb /path/to/rescue.log On my (example) system, we will be cloning /dev/sda to /dev/sdb.

This is usually achievable through the lsblk and blkid commands.
