With light I/O drives can last much longer that the warranty. I try to replace drives on high I/O boxes when they reach end of warranty. The most recent drive failures I have encountered involved very full disks and user complaining about slowdowns. In each case, smartctl showed errors, and for the few that were still under warranty the smartctl results were enough to get the authorization to return a drive for warranty replacement. > > Any thoughts on making sense of smrtctl are appreciated. > > Thanks, > > Bob > > > > smartctl 6.5 2016-05-07 r4318 [x86_64-linux-4.9.13-201.fc25.x86_64] > (local build) > Copyright (C) 2002-16, Bruce Allen, Christian Franke, > www.smartmontools.org > > === START OF INFORMATION SECTION === > Model Family: Seagate Pipeline HD 5900.2 > Device Model: ST3500312CS > Serial Number: 5VV9WJQQ > LU WWN Device Id: 5 000c50 0490e4346 > Firmware Version: SC13 > User Capacity: 500,107,862,016 bytes [500 GB] > Sector Size: 512 bytes logical/physical > Rotation Rate: 5900 rpm > Device is: In smartctl database [for details use: -P show] > ATA Version is: ATA8-ACS T13/1699-D revision 4 > SATA Version is: SATA 2.6, 3.0 Gb/s (current: 1.5 Gb/s) > Local Time is: Wed Mar 15 13:01:12 2017 EDT > SMART support is: Available - device has SMART capability. > SMART support is: Enabled > > > 9 Power_On_Hours 0x0032 074 074 000 Old_age Always > - 23096 > 10 Spin_Retry_Count 0x0013 100 100 097 Pre-fail Always > - 0 > 12 Power_Cycle_Count 0x0032 100 100 020 Old_age Always > - 85 Try to find the warranty period. I don't trust drives past the warranty period. but use them for non-critical roles if I think they were not used for high I/O workloads. We need to see the full report, but the error reports are pretty easy to spot. see: https://www.thomas-krenn.com/en/wiki/Analyzing_a_Faulty_Hard_Disk_using_Smartctl#Displaying_the_Test_Results -- George N.
