 * **I am using JMicron drive enclosures and some of my drives are not appearing.**
 
     This is likely because JMicron controllers incorrectly report identical serial numbers and other data which confuses various systems.
+    |omv| provides an `UDEV rules database <https://github.com/openmediavault/openmediavault/pull/746>`_ which will fix that issue for several USB PATA/SATA bridge controllers.

-    You will also need to create :file:`/root/serial.sh` containing the following::
-
-        #!/bin/bash
-        /sbin/hdparm -I /dev/$1 | grep 'Serial Number' | awk '{print $3}'
+        KERNEL=="sd*", ENV{ID_VENDOR}=="JMicron", SUBSYSTEMS=="usb", PROGRAM="serial_id %N", ENV{ID_SERIAL}="USB-%c", ENV{ID_SERIAL_SHORT}="%c"
 
     This will ensure that unique paths are created based on the serial number of the actual drives and not the enclosures.
