Good afternoon.

 

I ordered a new hard drive to add to my array. It arrived today and I attempted to insert it. For some reason, it wasn't being recognized in the hot-swap bay I was using, so to test it, I pulled one of the other drives and inserted it there (just to see if it was getting power), it was. So I moved the new drive to another bay (where it got power) and re-inserted the one I had temporarily removed.

 

When I went back to unRAID, I was seeing a red X on Disk 10 with the error "Device is Disabled, Contents Emulated" on mouseover.

 

The new drive is showing up in the "Unassigned Devices" list.

 

Both of the drives in question (the disabled drive and the new drive) are exactly the same model; ST4000DM004.

 

I'm really not very good at this. How can I go about either correcting the problem or rebuilding the drive before I attempt to add the new one?

 

Thanks.

It's been a while since I've tested this, so by all means wait for someone else to chime in, but from what I recall, unRAID won't auto-add a drive to the array, even if it's the same one that was just removed.

 

So to resolve this, you can stop the array, assign the drive back to the array, and let it rebuild. Then you can stop the array again, increase the number of array drive slots by one, and add your new drive.

That seems to be working. Letting it rebuild now. Probably going to take a few decades.
