May 15, 201610 yr The other day I noticed that one of the disks in my array had failed. it had a red x icon next to it and said device is disabled, contents emulated. So i bought a new drive and replaced it. After replacing the drive, I powered the system back up assigned the new disk to disk 10 (the one that had failed) and then started up the array. It said it would rebuild the data on to that new drive. The array did start back up but it never rebuild the data on to the new drive. It just still had the red x next to it. Right now my array is stopped and I am on the main tab where you assign drives. Disk 10 is still assigned to the new drive that I put in and I'm not sure how to get the system to rebuild the data onto the new drive. Could someone please point me int he right direction?
May 15, 201610 yr Community Expert Go to Tools - Diagnostics and attach the complete diagnostics zip. Also a screenshot. Won't hurt (except maybe your wallet) to have bought another drive but more often than not the problem is a connection or something and not really a bad drive.

May 16, 201610 yr Community Expert disk0 (parity) and disk1-7 OK, disk8 has 4 pending, disk9 OK, disk10 replaced, and disk12 OK. No disk11, is that correct? Looks like it had a problem talking to disk10. Check connections and cables, both power and sata.
May 16, 201610 yr Author no disk 11 is correct. so I shut down, removed and reseated both ends of each sata cable in the top drive cage where disk 10 lives and then powered back up. before startign the array, i set disk 10 to not installed in the main tab. then I started the array. stopped the array, and then assigned disk 10 to the new drive again and started the array back up and now it is rebuilding the data. so far so good. and the good news is that if it was just a cable, then after the rebuild I can throw the old drive back in and expand the array. thanks for your help with that!
May 16, 201610 yr Community Expert If the rebuild is successful you should do something about the pending sectors on disk8.
May 16, 201610 yr Author I appreciate thit advice! Could you elaborate a little on what I could do to remedy that? does that mean that drive needs to be replaced?
May 17, 201610 yr Author Thanks for that info! I tried unassigning and reassigning the disk to get it to rebuild and now if I go to the dashboard tab in the smart status row I get the yellow warning icon on disk 8. If I click on that and look under attributes I see two items hi lighted in yellow. One is reallocated sector count. Value:100 Worst:100 Threshold:10 Raw value 1 The other is reported uncorrect Value:100 Worst:100 Threshold: 0 Raw value: 983041 Does that mean the drive is failing and should be replaced?
May 17, 201610 yr No, just means you will want to keep an eye on it. Both have VALUE's of 100. The Reported Uncorrect RAW number is so far out of range that I would ignore it. Its WORST has not budged below 100. If your unRAID is up to date, you can acknowledge each of the SMART indicators, and turn the yellow back to green.
May 18, 201610 yr Author I am on 6.1.6 so it looks like I am a couple versions behind. I just downloaded the 6.1.9 zip file. what is the quickest way to upgrade?
May 18, 201610 yr Author nevermind - i just found that under the plugins tab there is an entry for unraid server od and i just ran the update there. that is an AWESOME feature. Might be worthwhile on the downloads page on the website to put a note on there telling us old school users that this is the easiest way to upgrade.
