January 29, 20233 yr Received a notification this morning that there were read errors on Disk 1 (612). It looks as if it happened during a parity check. I'm not quite sure what the best steps to take are. Attached is my diagnostics, maybe you can spot and advise what I should do. Other than these notifications, the system is running normally without anything odd happening. Thanks. nas-diagnostics-20230129-1543.zip
January 29, 20233 yr Community Expert Check connections on disk1, power and SATA, both ends, including splitters. Run another non-correcting parity check.

So I changed sata cables made sure everything was seated properly, I even went to the extent of rebuilding it. Still showing read errors and parity errors after non correcting check.

Last week parity check completed with 3 errors and yesterday with 0. But disk1 slowly creeps with errors, sitting at 293 so far.

February 20, 20233 yr Community Expert They are again logged as disk errors, and since SMART is showing some issues I would replace that disk.

Oh weird, I thought there wasnt any issues as the test completed fine. I had a feeling it was time to replace this disk. I think it was the most used out of the entire array.
