 ### How do I pass-through a disk?

+   For use with physical disks this method provides little advantage over using an image and is not recommended. You can add the device to your compose file like this:

-    - /dev/disk/by-uuid/12345-12345-12345-12345-12345:/disk2
+    - /dev/sdc:/disk1
   ```
 
-  The device needs to be totally empty (without any partition table) otherwise DSM does not always format it into a volume.
-  
-  Make sure to bind the disk via its UUID (obtainable via `lsblk -o name,uuid`) instead of its name (`/dev/sdc`), to prevent ever binding the wrong disk when the drive letters happen to change. 
- 
-> [!CAUTION]
-> Do NOT use this feature with the goal of sharing files from the host, they might all get lost without warning when DSM creates the volume.
