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

The script works in DSM 7 and DSM 6.

• 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 file 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".
• Checks that M.2 volume support is enabled (on supported models).
• Makes DSM recheck disk compatibility so rebooting is not needed (DSM 7 only).
• Reminds you that you may need to reboot the Synology after running the script (DSM 6 only).

Planned updates:

• Allow unsupported M.2 drives for use as volumes in DSM 7.2 (for models that supported M.2 volumes).
• Detect any connected expansion units and get the model(s) and edit the correct expansion unit db files.
  • Or add support for users to specify their expansion unit model(s) as arguments.
  • Or maybe use the shotgun approach and update all expansion unit db files.

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: For DSM 6, after you first run the script you may need to reboot the Synology to see the effect of the changes.

There are 3 optional flags you can use when running the script:

• -showedits or -s to show you the changes it made to the Synology's compatible-drive database.
• -force or -f to disable "support_disk_compatibility". This should be needed if any of your drives weren't detected.
  • If you run the script without -force or -f it will re-eanble "support_disk_compatibility".
• -m2 or -m to prevent processing M.2 drives.

See How to schedule a script in Synology Task Manager

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

sudo /path-to-script/syno_hdd_db.sh

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 /path-to-script/syno_hdd_db.sh -showedits

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