How to rebuild an existing drive?

[Ryan_M 0]

I had a drive redball and another member here had a look at the smart report and didn't notice anything out of the ordinary and suggested checking connections and rebuilding the disc. I also replaced the sata cable as a precaution. So now how do I rebuild that drive? I thought removing it from the array, rebooting, then adding it back in the old spot would prompt a rebuild as if I put in a new drive but when I reboot the drive is back in the old spot as if it had never been removed. Sorry I'm probably missing something simple but I can't find it.

Just one small detail missing, you have to make unRAID forget the drive first.  So unassign it, start the array then stop it again, then re-assign it.  To forget it, the array has to be started without it.

 

I should probably add that to Replacing a Data Drive.

Thanks! Your suggestion worked perfectly - rebuild in progress. And for what it's worth, the guide in your link was what I was following.

I've added notes about this and other issues to that wiki page, and to the Re-enable the drive wiki section, and to much of the Troubleshooting page, updating it for v6.  I would appreciate reviews of it for accuracy.  Any suggestions and improvements welcome!
