Hi, I just installed WD RED 3TB drive in my NAS. While it’s idle, i t’s constantly clicking
which is simply annoying :). Is that normal or is it some kind of failure? There seems to be no drive activity (according to system disk monitor and LED on the case)
Hello, this is not normal I have 2 WD Red in RAID 0 on my desktop and my video card makes more noise than them. Run the DLG on the drive and see the health status of it.
I managed to finally solve the clicking. Backed up my data,
reconnected drive to ESXi as RDM. Formatted in ext3 and retrieved the
data. No clicking from now on
