August 10, 20178 yr Following a read error on a disk in a Synology, I took the opportunity to upgrade my home NAS (Hello, Unraid!). Ordered some hardware, moved all the data safely over to Unraid and now I've got this extra disk.... I was trying to repair the disk while in the Synology, but wasn't having luck. Out of curiosity I tossed the disk in to my new Unraid box and cleared/formatted the disk then kicked off an extended SMART self test. Here are the results... Num Test_Description Status Remaining LifeTime(hours) LBA_of_first_error # 1 Extended offline Completed without error 00% 18475 - # 2 Extended offline Completed: read failure 90% 18341 101520764 # 3 Extended offline Completed: read failure 90% 18323 101520763 # 4 Extended offline Completed: read failure 90% 18316 101520763 # 5 Extended offline Completed: read failure 90% 18316 101520762 # 6 Extended offline Completed: read failure 90% 18313 101520761 # 7 Extended offline Completed: read failure 90% 18303 101520760 # 8 Extended offline Completed: read failure 90% 18295 101520760 # 9 Short offline Completed without error 00% 18211 - #10 Short offline Completed without error 00% 17492 - #11 Short offline Completed without error 00% 16748 - #12 Short offline Completed without error 00% 16029 - #13 Short offline Completed without error 00% 15286 - #14 Short offline Completed without error 00% 14622 - #15 Short offline Completed without error 00% 13208 - #16 Short offline Completed without error 00% 12491 - #17 Short offline Completed without error 00% 11748 - #18 Short offline Completed without error 00% 11028 - #19 Short offline Completed without error 00% 10285 - 7 of 7 failed self-tests are outdated by newer successful extended offline self-test # 1 As you can see... there was a read failure then I ran the test a few more times while I was trying to mess with the sector on the command line. Final run is immediately after clearing the drive with Unraid. Now it looks like a clean drive.... should I trust it? or should I just consider it trash?
