Woke up this morning and noticed this disk has thrown 6974 errors.  It still shows green. https://wiki.unraid.net/Troubleshooting#Hard_drive_failures This FAQ suggests nothing to worry about, but it says no-zero.  6974 seems a bit more worrisome than non-zero. Should I get a replacement?   For what it's worth, I'm copying a ton of data to the array right now (and for the last few days).
