SMART Monitoring negative Value meaning

[Senoo.]

Hello everyone,

i am completly new to zabbix and had an external HDD with a SMART Status of Abnormal (2).
Checked the HDD and the status seams to be right. So after replaceing the external HDD i have the following Error on the SMART Value:
Value of type "string" is not suitable for value type "Numeric (unsigned)". Value "-1"

Is this due to Zabbix which cant read the SMART Data of the device?
What does "-1" mean in this context?

snmpget returns the same value of -1

Zabbix Server Data:
Ubuntu 24.04
Zabbix Version: 7.0.5
Database: PSQL
Web Server: Nginx

SNMP Check on QNAP NAS

Kind Regards

Hello,
Looks to me like NAS failed to communicate the values in a proper way.
If you could share the exact NAS type, i could explore further.

Kind regards
