Just yesterday my Server that has been booting up faithfully for years all of a sudden stopped and showed the error:
Port 4 - HGST HDN72404OALE640 - SMART status bad. Backup, exchange, replace drive.
When I continue to boot it starts the array just fine and in UnRaid SMART reports are just fine. For the time being I disabled in the BIOS the check for SMART and it boots now just fine. Should I be concerned?
The problem is I can't correlate Port 4 to the disc as I have 3 other discs with the same labeling it is the part that follows that is different. I have sdf, sdg, sdh & sdi (the parity) that all start with the number that the BIOS SMART test reports.
I am open to suggestions but since I only check the UnRaid GUI should I correct this BIOS flagging or just keep an eye on the UnRaid SMART report?
