 * Optionally disable DSM's "support_memory_compatibility" to prevent <a href=images/ram_warning.png/>non-Synology memory notifications</a>.
 * Optionally edits max supported memory to match the amount of memory installed, if installed memory is greater than the current max memory setting.
     * DSM only uses the max memory setting when calculating the reserved RAM area size for SSD caches.
+* Optionally disables Western Digital Device Analytics (aka WDDA) to prevent DSM showing a [warning for WD drives that are 3 years old](https://arstechnica.com/gadgets/2023/06/clearly-predatory-western-digital-sparks-panic-anger-for-age-shaming-hdds).
+    * DSM 7.2.1 already has WDDA disabled.
 * Enables M2D20, M2D18, M2D17 and E10M20-T1 if present on Synology NAS that don't officially support them.
 * Checks that M.2 volume support is enabled (on models that have M.2 slots or PCIe slots).
 * Enables creating M.2 storage pools and volumes from within Storage Manager **(newer models only?)**.

-**Note:** If you have some Synology drives and want to update their firmware run the script **without** --noupdate or -n then do the drive database update from Storage Manager and finally run the script again with your preferred options.
+**Notes:** 
+- The -f or --force option is only needed if for some reason your drives still show as unsupported in storage manager.
+    - Only use this option as last resort.
+    - Using this option will prevent data deduplication from being available, and prevent firmware updates on Synology brand drives.
