I have a HD in my unassigned devices, I'd like to copy some data to it.  It was at one point part of the array but I replaced the drive a long time ago with a larger drive.  I cannot mount the drive, and it's just showing as "POOL" which is greyed out.  How do I make the drive useful again in unassigned devices?

 

I just did "new config" and only kept the "array" data, the array is now rebuilding parity but this made no difference to this drive.

 

Thanks

Just replying to this myself.  There was no way in UnRaid that I could see to blank the drive (within the GUI at least) so I removed it and used a Windows machine to delete all partitions and reformat the drive to NTFS.  This then allowed it to work in UD.

The disk showed 'Pool' because the drive was formatted without a partition and UD does not know how to handle devices formatted that way.  Your solution was a good way to handle it.
