Magician 7.0.1 was the last version that was working on my PC. I do have 2 NVE drives: 980 PRO, 990 PRO and ADATA SX8200 PRO. When I upgrade to latest version the Magician hangs. The same with bootable drive when I'm was trying to update firmware on 990 PRO. It simply hangs on SCANNING operation.
I found out that removal of the ADATA drive solves the problem. I hope it is just a bug not a Samsung way to enforce only their drives in the system.
