djonesax Posted April 22, 2021 Share Posted April 22, 2021 I have a disk that unraid disabled because there were 2 sector errors. I replaced the drive and the new drive is rebuilding now. My question is, can I repair this drive some how? Is there a tool that I could use on it that find the bad sectors and mark them as bad or something? Quote Link to comment

In principle the firmware in the drives should reallocate bad sectors as soon as they are written to. Using the manufacturers test software should support this. Quote Link to comment

I am now doing a full overwrite on the drive and if all that works, I think I will just pop it back into the unraid array and see how it does. Quote Link to comment

It might be possible that bad sectors caused the write error, but as mentioned, usually the drive will just reallocate and keep on working and as far as Unraid is concerned nothing would be wrong, except for perhaps a SMART warning. We would have a better and more specific idea of what really happened if we could have seen the Diagnostics before rebooting. At the very least, SMART report for that disk would give us a better idea. Quote Link to comment

After I put it in my windows box and deleted the volume, I was able to give it a drive letter and see it in the disk utility. At that point I could get smart data but it just said there were no errors after running an extended test for almost a full day. Do you think its OK after doing a successful full overwrite, to put it back in the array and just monitor it for errors again? Quote Link to comment
djonesax Posted April 22, 2021 Author Share Posted April 22, 2021 The erase failed, I guess I'll toss the drive, after sledge hammering it. Here is all the tool gave me for smart data. Quote Link to comment
