July 19Jul 19 Can someone tell why, once or twice a year, one or more disks randomly decide to be error disabled?Most of the time I unassigned those and reassigned them to activate them, and that's it.Sometimes, like now, that does not help. Either while the data rebuild is running or after the rebuild is done, the disk will go into the error state again.That's what happened again:Disk 2 error disabled -> reassigned -> rebuild failed -> reassigned -> rebuild successful -> a few hours later, error disabled again...A few days after, Disk 3 also wants to be in an error state.Does anyone have an idea why this keeps happening? I'm tried of worrying about my data.Are the drives the issue here? Unraid does not recommend you use SMR drives but they should work: https://unraidcalculator.com/drive-recommendations.htmlThe SMART data looks fine.In the last thread I made the conclusion was a Hardware issue.Maybe there still is and I'm not seeing it? biggie-diagnostics-20260719-1330.zip
July 19Jul 19 Community Expert Solution It's not logged as a disk problem, looks more like power/connection issue, Check/replace cables, also any power splitters in use?
July 19Jul 19 Author Checked the SATA-connectors, and now the two drives are not recognized anymore:Tried a few times but no luck. They Sounds and feel like they have power...I ordered a new mSAS to SATA Cabel. Hopefully that will fix it.3 hours ago, JorgeB said:any power splitters in use?Not for these drives, but I use a Molex adapter.Since they seem like they have power, I don't think that's the issue.
