Thanks, the preclear finished thankfully without issues. To rebuild the data do I just follow the original steps but for the new drive?

I'm going to opt to do the preclear but I can't seem to find it within unraid itself. Is it done through an app? I found "Unassigned Devices Preclear" so I'm guessing I add that app and use it to preclear the drive before adding it to the array, is that about right?

Thanks. I did replace the cable originally and swapped the ports on the motherboard and its still happening so I guess it's time to replace the disk. Just a shame since I didn't really use it that much. Good thing I bought a replacement already. Any tips for checking the new drive to make sure it won't fail early?

The smart test completed, supposedly without issued though i'm not sure how that's possible when the drive has errors. Attached are new diagnostics and the smart report. Thanks again for your help. tower-smart-20250415-1116.zip tower-diagnostics-20250415-1116.zip

Well, I'm running the test and the disk doesn't sound good. I'm pretty sure I'm hearing clicking and grinding from the disk. I'll wait to see what the smart test results in and post updated diagnostics when it's done

Got it, thanks. I'm new to docker, I just have the one app running on it for some more info on my drives. Unfortunately, it looks like my feeling was right. The drive got kicked out of the array again when I was running a backup of one of my PCs to the NAS... diagnostics attached tower-diagnostics-20250413-2136.zip

sorry, i edited the post just before you posted

Yes I did the rebuild in maintenance mode and then stopped and started the array. Everything looks to be working well now. I'm just wondering about in the future if/when the drive gets kicked out again. tower-diagnostics-20250413-1424.zip

The rebuild completed without errors so I suppose I'm good to continue using the array. I'm wondering, however, if the disk keeps getting kicked out should I just come back with new diagnostics or make a new thread? I'm a bit concerned with the disk getting kicked out a few times now. tower-diagnostics-20250413-1226.zip

Thanks a lot for your help. I've started the rebuild and i'm crossing my fingers for zero errors for the disk. I'll report back when the rebuild is complete.

Hi, just a quick update. The extended self SMART test completed without error. It looks like it was stuck at 90% for some time but now it's completed.

Here they are tower-diagnostics-20250410-1651.zip

I'm running the extended self-test on disk2 but I believe it's stuck at 90%. I started the test yesterday evening and let it run overnight and it's still 90%...

Thanks for your help. That managed to get the disk back into the array and it was working well. Now after another parity check the drive was kicked out again, but once again SMART is showing no issues so I'm not sure what's going on. Am I dealing with a potentially bad drive? I have a replacement ready if needed. I attached a new diagnostics file and haven't restarted the system so hopefully it has some more information than last time. tower-diagnostics-20250409-1611.zip
