and may I add, when lauching HDtoolbox it will list the drives there under the uaehf interface, but clicking on any of them will show popup "This drive is not installed yet" etc...
As the 2nd SSD was simply a mirror backup, I cleaned it with diskpart and I can install/partition it again as expected, but since both drives behave identical, I wonder if this is a PFS AIO bug or a WinUAE bug ??
Seems that I lost all the precious work, and I am getting really irritated that my retro enthusiasm is getting tempered with these kind of unexplained setbacks.
