As the subject indicates, I just recently upgraded the firmware on my QNAP NAS TS-119 and noticed in the Volume Management section that my still fairly new (purchased NEW 4/2014) WD 4TB (4003FZEX) drive is being reported as having a SMART “warning” status (see screen capture below). I tried running the various diagnostic tests that the firmware offers in addition to verifying the file system but the warning status remains. Since the system doesn’t seem to be in a critical failure status and I haven’t noticed any abnormal operation, should I be overly concerned about this? Or should I start considering an upgrade and/or warranty replacement (5 years) from WD? Thanks in advance.
