+   It is possible to pass-through disk devices or partitions directly by adding them to your compose file in this way:

+    - /dev/sdb:/disk1
+    - /dev/sdc1:/disk2
   ```
 
-  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. 
-
-> [!IMPORTANT]
-> The device needs to be totally empty (without any partition table) otherwise DSM does not always format it into a volume.
