Description of problem:
 I am trying to install Fedora on an external HDD from a liveUSB of Fedora. 
After choosing "Installation Destination", I selected my external HDD for installing Fedora 23. 
Next it tells me I need to reclaim space. I made a partition (NTFS) of about 100GiB for installing Fedora. 
When trying to reclaim space from a partition on my external HDD I continually receive the following error. 
This happens before I can even begin the installation process. 
The fedora iso is verified.

Version-Release number of selected component:
anaconda-core-23.19.10-1.fc23.x86_64
