I swapped in a 1TB drive and an 80 pin cable into my unit. I went and formatted the new disk with the Hexen 2018 CD, and setup the Xbpartitioner with the extended partition at 948 GB in 64k clusters. So the space free for F shows 948 GB until I reboot into Unleashx. Then it becomes around 123 GB free. If I go into the menu and restart Hexen, it boots up and shows the correct free space. What gives? I have r reformatted several times
