## Create disk image

### ddrescue

This command copies as much as possible from a failing drive into a disk image

[shroot]

```
ddrescue -n /dev/sdX copy.img rescue.map
```

[/shroot]

The second round uses multiple tries in attempts to also rescue previously identified bad blocks.

[shroot]

```
ddrescue -d -r3 -n /dev/sdX copy.img rescue.map
```

[/shroot]
