Reinstall Synology DSM

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.

  1. Use a pin to push reset button until the first beep.
  2. Push again beep within 10 seconds. It will beep 3 times and restart.
  3. After restart, you will be asked to re-install your DSM as below.
