@Lonnie_LeMaster Welcome to the Rockstor community. From the message it would appear that this drive is currently in use and so the wipefs command is failing as a result ie “Device or resource busy”. Make sure that the drive is not currently mounted as that would do it. A screen grab of the Disks page might help, also the output of the “mount” command would be helpful as it should show what is currently using this drive.

Hope that helps.
