Note:
1 When the drive LED indicator is red/orange, we recommend you sign in to DSM and go to Storage
Manager > HDD/SSD for more information.
2 Please try to restart your Synology NAS or re-insert the drives, then run the HDD/SSD manufacturer's
diagnostic tool to check the health status of the drives. If you can sign in to DSM, please run the built-in
S.M.A.R.T. test to scan the drives. If the problem remains unresolved, please contact Synology Technical
Support for help.
3 If the ALERT LED continuously blinks orange, this indicates there are system errors such as fan failure,
system overheating, or volume degrade. Please sign in to DSM for detailed information.
