December 25, 20205 yr Happy Holidays fellow UnRAIDers, Does anyone happen to know if there’s a quick reference or secret decoder ring for understanding various disk errors on parity checks and/or SMART tests? I run a parity check every month and have had read errors on one of my drives the past two months. I am ready to replace it with a new drive, but before tossing out what could be a good drive (but with a bad cable), I thought I’d check with the collective knowledge of folks who know a whole lot more than me. Attached are the results of an extended SMART test and a screenshot of the errors I get with the parity check. Thanks for the help, and Merry Christmas!

December 25, 20205 yr Author All of the disks say “healthy” on the dashboard page. When I run a quick SMART test on the drive in question, it passes. However, it failed the extended SMART test (with the previously attached log).
December 25, 20205 yr Community Expert You need to also monitor attributes 1 and 200 on WD Reds. Click on each to get to its settings. That disk wouldn't say healthy if you added those.
December 25, 20205 yr Author Thank you for the time and help! So I presume you mean I should add “1,200” to the custom attributes field? As suggested, it then says “failed” for that drive on the dashboard. Reading between the lines, it sounds like I do, in fact, have a bad drive, then. Out of curiosity, though, from those errors are you able to explain what is failing in the disk? Any reason for me to worry about what has been written to the parity drive? Also, I take it that I should start monitoring attributes 1 and 200 on my other 4 WD reds? Again, I really appreciate your help

December 25, 20205 yr Author Thank you for all the info...I’ll be keeping a better eye on attributes 1 and 200 meow. Think I’m ok to just replace and repair from parity, then? Merry Christmas!
