May 30, 20188 yr I started getting some UNC errors on a drive today and i ran an extended smart test. Online some people are saying its not that serious, the drive isn't making any noises if it faulty ? Below is the output of the drive smart. smartctl 6.6 2017-11-05 r4594 [x86_64-linux-4.14.40-unRAID] (local build) Copyright (C) 2002-17, Bruce Allen, Christian Franke, www.smartmontools.org === START OF INFORMATION SECTION === Model Family: Western Digital Red Device Model: WDC WD30EFRX-68EUZN0 Serial Number: WD-WCC4N6KL7C79 LU WWN Device Id: 5 0014ee 26349a6c9 Firmware Version: 82.00A82 User Capacity: 3,000,592,982,016 bytes [3.00 TB] Sector Sizes: 512 bytes logical, 4096 bytes physical Rotation Rate: 5400 rpm Device is: In smartctl database [for details use: -P show] ATA Version is: ACS-2 (minor revision not indicated) SATA Version is: SATA 3.0, 6.0 Gb/s (current: 6.0 Gb/s) Local Time is: Wed May 30 23:31:35 2018 AEST SMART support is: Available - device has SMART capability.
