So i am running an HP HBA 222 on my DL380P G8 with 3,5" HP SAS Disks attached. They show up just fine on unraid, smart is partial readable compared to my Crucial MX500s - on the HP Disks, i am getting the following error: Non-medium error count: 518. The numbers seem to be not increasing, only when booting up, it adds like one counter to it. Should i be worried or is it possible to get rid of those errors?
