June 24, 20224 yr Hello everyone. I attached the diagnostic file, but I will explain everything here too. I have 3 data drives (6TB, 4TB, 2TB), 1 parity (6TB). yesterday my 6TB drive had a single write error. I then shut down everything and reconnected every sata connection, as I have replaced a disk a few days earlier, so it's not impossible that I loosened some cable mistakenly. Hoping that the disk is not fully toast, I started a parity sync. This ran fine until 30%, then the speed dropped to around 200KB/s for at least 5 Minutes, after that, the 2 TB drive reported read errors, after a few minutes it was about 3000 Errors (but it did not increase any further). During and after those errors, the speed continued with 200 KB/s. But, (luckily?) it finished reading that drive (the general progress of the parity snyc reached more than 2 TB) and currently is continuing to parity sync. What can I expect now? I'm hoping I will only have a few corrupted files, or will there be more severe damage? Also, what should I do now? I'm currently ordering a replacement drive for the 2 TB disk. The 6 TB drive seems to work fine during the parity sync and has not encountered any further error (to my knowledge). I'm guessing you will recommend me to also replace the 6 TB drive? tower-diagnostics-20220625-0128.zip Edited June 24, 20224 yr by lustigpeter pressed enter by mistake
June 24, 20224 yr I'm guessing you hit enter before you finished the post. You can just reply to this thread and finish your thought.

Are you saying I don't have to replace any of those? Edited June 25, 20224 yr by lustigpeter

You can run ane extended SMART test, if it passes check/replace cables. 43 minutes ago, lustigpeter said: Also what about the 6TB data disk that had the write error? Diags are after that error, they start over after every reboot, so cannot comment.
