+## 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
+```
