October 26, 201213 yr I pre-cleared four drives and they all cleared ok. When adding them to my array, they apparently are clearing again? Both the clearing machine and the live array are using the exact same version of unRAID and I am using the latest pre-clear script. Any idea why it would not recognize those drives as already pre-cleared?

October 26, 201213 yr Author Ah wait... I just went and checked and was going to take a screenshot so you can see the serials match and it appears that they are ready to format. It's been a while since I've added a new drive but I can tell you it DEFINITELY said "Clearing" and was going 1% at a time for quite some time. Was it merely CHECKING the clearing and not really clearing again?
October 26, 201213 yr Author Actually it appears that the drives had HPA on them which maybe triggered it?

The pre-clear script should terminate and a command line should return. There should be nothing to kill. Are there reports in /boot/reports?
October 26, 201213 yr Author I killed the pre-clear reports as each finished. That report was from the last drive. that was in the preclear_reports folder. I suspect it was because there was HPA on the drives and am going to re-clear them after removing the HPA. Posted another post asking advice on my "fix" as I figured I have a different issue now. Thanks for your reply here.

(You are two versions behind, as of this post, it is 1.13, you are on 1.11 and 1.13 has been out for quite a while.) What version of unRAID are you running? There was at least one (fairly recent) version that would not recognize a pre-cleared disk properly. If your MB added the HPA after the disks were cleared, they would no longer be detected as pre-cleared. In the same way, if you remove the HPA after pre-clearing them, they will no longer be detected as pre-cleared. If you previously assigned the drives to an array, they are no longer pre-cleared.
October 26, 201213 yr Author Ah, interesting. I have three fobs with unRAID on it and I wonder if that one never got the new clear script. I am running 4.7. I cleared them on a mobo that I know doesn't create the HPA as I have checked previously. I also have cleared 12 other drives on that same mobo so I know that's not the issue. The drive did however come from a DIFFERENT system that I can not say with any certainty didn't put that partition on there. I posted it's own thread as to my plan of attack to fix which basically would be remove the drives one at a time, remove the HPA, re-clear and add back. Rinse, repeat until all drives have been fixed.
