May 26, 20215 yr I recently had some errors during my parity check so I did not think much of it and tried to repair it. The parity repair was running an average of 600kb/second on a 12tb drive. I noticed that another drive was emulated so I tried to drop one of the two parity drives to replace the emulated drive. That also was running the repair at under 1mb/s (average of 600kb/s). Then I reverted the drives back into their original position. Smart is showing no errors so I tried using a docker of Drive Speed and the results I got from it where: Even the slower drives have speed on the benchmark that are higher than what I am getting on the parity repair. So I am out of ideas on how to proceed. I have attached my diagnostic logs and my specs are: Any help is deeply appreciated. tower-diagnostics-20210525-2305.zip Edited May 28, 20215 yr by ONI no longer needed the log files.

Good news is that my speeds have been fixed by replacing all my sata cables. The bad news is that two of my drives still show as unmountable unless I format them so I would lose all the data they currently contain. Any ideas on how I can get them back online without wiping them?

May 28, 20215 yr Author Thank you for all your help. I am psyched that I had no drive loss. With the current prices of storage and potential loss of tons of data I was worried I had failed drives. Without your help I would of probably taken the loss and went storage hunting.
