Hello,
I bought a 6TB WD Red in November 2015 and have been using it an Linux server since then (Openmediavault).
By chance, I have just come across a page the suggests that there might be an issue with the Harddrive’s firmware, that needs to updated:
I am not entirely sure what the implications of this are but is there a way to check whether my Harddrive already has the fix or whether I do indeed need to add it?
