Observation: The Synology NAS operating system reports an HDD or SSD Health Status Warning for a Seagate drive.
Perform a separate SMART test on the drive which is reporting a Health Status warning. If the drive passes this test, you can ignore the warning and continue to use the drive in the NAS. This will not affect usage or data integrity.
If the drive does not pass the SMART test, please contact Seagate Support Services.
