Unexpected info about the disk space

[Hakuna]

I have recently experienced a rather interesting problem.
We are using self hosted version and client with problem has installed zabbix agent 2 v6.4.2 on the server.
I have set a trigger for information on occupied server disk space. Everything has worked properly for years.
However, recently I got a message: "Free disk space is less than 20% on volume T:"
I've got only volume C: and D:.
I checked the drive lettering and the extra part on the recovery - there is no "T" drive.

Do you have any ideas why this has appeared?

Hi,
Has anyone ever connected a flash drive to this server?
Have you checked the Event Log of this Windows server?

Are you using Discovery to find drives? If yes, check when the "T" drive was detected and added to the monitoring. Then go to the Windows Event Log and check what happened by date.

Right! I checked the log and spoke with our technics. There was a flash drive in that moment. It is so obvious...
Thank you!
Greetings.
