Add your SATA or SAS HDDs and SSDs plus SATA and NVMe M.2 drives to your Synology's compatible drive databases, including your M.2 card and Expansion Unit databases.

The script works in DSM 7, including DSM 7.2, and DSM 6.

It also has a restore option to undo all the changes made by the script.

• Gets the Synology NAS model and DSM version (so it knows which db files to edit).
• Gets a list of the HDD, SSD, SAS and NVMe drives installed in your Synology NAS.
• Gets each drive's model number and firmware version.
• Backs up the database files if there is no backup already.
• Checks if each drive is already in the Synology's compatible-drive database.
• Adds any missing drives to the Synology's compatible-drive database.
• Prevents DSM auto updating the drive database.
• Optionally disable DSM's "support_disk_compatibility".
• Optionally disable DSM's "support_memory_compatibility" to prevent non-Synology memory notifications.
• Optionally edits max supported memory to match the amount of memory installed, if installed memory is greater than the current max memory setting.
• Enables M2D20, M2D18, M2D17 and E10M20-T1 if present on Synology NAS that don't officially support them.
• Optionally enables immutable snapshots on models older than '20 series running DSM 7.2.
• 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?).
• Makes DSM recheck disk compatibility so rebooting is not needed if you don't have M.2 drives (DSM 7 only).
  • If you have M.2 drives you may need to reboot.
  • Reminds you that you may need to reboot the Synology after running the script.
• Checks if there is a newer version of this script and offers to download it for you.
  • The new version available messages time out so they don't prevent the script running if it is scheduled to run unattended.

See How to download the script for the easiest way to download the script.

You would need to re-run the script after a DSM update. If you have DSM set to auto update the best option is to run the script every time the Synology boots, and the best way to do that is to setup a scheduled task to run the the script at boot-up.

Note: After you first run the script you may need to reboot the Synology to see the effect of the changes.

There are optional flags you can use when running the script:

-s, --showedits       Show edits made to <model>_host db and db.new file(s)
-n, --noupdate        Prevent DSM updating the compatible drive databases
-m, --m2              Don't process M.2 drives
-f, --force           Force DSM to not check drive compatibility
-r, --ram             Disable memory compatibility checking (DSM 7.x only) and set max memory to amount of installed memory
-w, --wdda            Disable WD WDDA
-i, --immutable       Enable immutable snapshots on models older than 20-series (DSM 7.2 and newer only)
    --restore         Undo all changes made by the script
    --autoupdate=AGE  Auto update script (useful when script is scheduled)
                      AGE is how many days old a release must be before auto-updating. AGE must be a number: 0 or greater
-h, --help            Show this help message
-v, --version         Show the script version

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.

See How to schedule a script in Synology Task Scheduler

You run the script in a shell with sudo -i or as root.

sudo -i /path-to-script/syno_hdd_db.sh -nr

Note: Replace /path-to-script/ with the actual path to the script on your Synology.

If you run the script with the --showedits flag it will show you the changes it made to the Synology's compatible-drive database. Obviously this is only useful if you run the script in a shell.

sudo -i /path-to-script/syno_hdd_db.sh -nr --showedits

Note: Replace /path-to-script/ with the actual path to the script on your Synology.
