February 14, 20242 yr Hello together, Since a crash of my server I have some read errors on my second HDD. Could someone help me to solve it? tower-diagnostics-20240214-2220.zip
February 15, 20242 yr Community Expert It's logged as a disk problem and SMART doesn't look great, run an extended SMART test.
February 15, 20242 yr Author hi, I did the test and the result looks quite positive. Any idea what happened or what to do?
February 15, 20242 yr Community Expert Since the test passed technically the disk is OK, at least at this moment, but based on these and the previous logged errors: ID# ATTRIBUTE_NAME FLAGS VALUE WORST THRESH FAIL RAW_VALUE 1 Raw_Read_Error_Rate POSR-K 199 199 051 - 31282 200 Multi_Zone_Error_Rate ---R-- 194 194 000 - 2506 I would expect more errors very soon, you can try and give it another chance but most likely will need to replace it in the near future.
February 15, 20242 yr Author Thanks a lot for the support - what ist the best way to replace it. Rather to rebuild by parity or other way.
February 15, 20242 yr Community Expert You should click on each of your WD disks and add those attributes, 1, 200, for monitoring.
