Hello
I don't know if anyone can help with this but I suspect it might be a bug in the plugin.
I just installed the latest version of Unnassigned Devices - dated 2018.04.09 onto Unraid v 6.5.1
I did a conversion of a VM disk directly to a new SSD drive, unassigned to the array, and it created the expected partitions. But each of the partitions are listed as 0 bytes. I updated the VM to use the disk and it did work, although slower than I had expected, but the sizes of the partitions are still showing zero.
Below is a screenshot of what I see. Any ideas?
