-!!! note "Zapping the device"
-    The Ceph OSD container will refuse to destroy a partition containing existing data, so it may be necessary to "zap" the target disk, using:
-    ```    
-    docker run -d --privileged=true \
-    -v /dev/:/dev/ \
-    -e OSD_DEVICE=/dev/sdd \
-    ceph/daemon zap_device
-    ```
+!!! warning "Zapping the device"
+    The Ceph OSD container will normally refuse to destroy a partition containing existing data, but above we are instructing ceph to zap (destroy) whatever is on the partition currently. Don't run this against a device you care about, and if you're unsure, omit the "OSD_FORCE_ZAP" variable
