Recently, I boot my Synology DS214SE with error message about my hard drive. After re-initializing and re-installing packages, it still doesn’t work properly. Therefore, I decide to re-install DSM.
How to reset your Synology NAS has very detail, step-by-step, instructions.
- Use a pin to push reset button until the first beep.
- Push again beep within 10 seconds. It will beep 3 times and restart.
- After restart, you will be asked to re-install your DSM as below.

If you want to install a different version, check Downgrade Synology DSM.
Interesting! Thanks for update. I already solve my DS214SE earlier this year and cannot confirm your steps.

I found my synology with http://find.synology.com . Make sure you authorize your NAS to be found by this service. Excellent!
