When you'll mount your HD, Windows will recognize it as unformated drive. OFC you will press cancel in the format dialog


Start WinUAE as Administrator and go to Hard Drives tab on the left and click the button "Add Hard Drive"
(In my example, I have 2xHDF files mounted as DH0 and DH1 partition in the emulator by default)

On the windows that will appear, you click on the combo box (arrow on the right)

You choose your HD from the list. You can recognise it easily since it's the only one with RDB declaration

Then you click the "Read/write" option and click "Add hard drive"

Once you're ready... just click the "Start" button and the Emulator will start...

Just for info, you can see my 8GB Backup CF mounted on my test ECS A600 clone environment
