Hey y'all,
I'm trying to set up a new server and decided to preclear my new shucked HDDs before making an array. Unfortunately, I wasn't really aware that the preclear would essentially stress test the drives so all four of them ended up overheating on the first night (no airflow). I also learned shortly afterwards that the RAM I had started on was faulty. Lastly, because of the RAM issues, the server was restarted multiple times during the process where the preclear successfully resumed when logged back in. Well, two of the preclears have fully finished now and it looks like the post-read verification failed on both.

I take it my next steps should be to rerun the entire preclears on all four drives to hopefully get a pass. With airflow, new ram, and no restarts it should work out, eh?
Did the overheating for a night permanently damage the drives? Would a short/long smart test be more adequate at this point?
Thanks!
