May 12, 20251 yr The title pretty much says it all. I missed an email warning from 3.5 days ago that told me it was disabled and being emulated. There haven't been any changes to the server lately (hardware wise) other than an upgrade from v6.12.10 to 7.01 a week ago (which went without a hitch and only took about 10 minutes). Short SMART Self Test shows no problem with the disk. Is this disk actually bad or might it be a cable problem. I did have a cable problem last year but it showed itself as UDMA SMART Errors, but this looks different. I've attached my "unraid-diagnostics-20250512-0009.zip" file. Thanks for any help you can provide. unraid-diagnostics-20250512-0009.zip

You need the Extended one to see if the drive is probably OK.

May 12, 20251 yr Community Expert Wait for the test to complete, but it's not logged as a disk problem, most likely a power/connection issue.

May 13, 20251 yr Author Well, it looks like "No Errors Logged" during the Extended Self Test. What do you think best steps are to move forward? I was thinking about rebuilding the drive back onto itself per these instructions (https://docs.unraid.net/unraid-os/manual/storage-management/#rebuilding-a-drive-onto-itself) after shutting down the server and reseating the connections. I have a 20TB replacement drive showing up on Thursday, just in case.
May 13, 20251 yr Community Expert No obvious reason I can see why you should not rebuild the disk onto itself, but first check that the emulated disk is showing all the that you expect. I think from the diagnostics that it will be disk 10 and it looks like the emulated drive is mounting OK. Having said that if you have a replacement 20TB disk on the way you may want to take the chance to upgrade disk10 to 20TB instead to get some extra space as you already have a 20TB drive as parity? Since you only have a single parity drive this would be slightly safer as it allows you to keep the old disk10 intact just in case another disk fails during the rebuild of disk10. After the rebuild completes successfully you could then add the old disk10 to the array to a new drive slot. Alternatively you may decide you want to use the new 20TB drive as a second parity drive so you could handle 2 simultaneous disks having problems in the future.
