You won't be able to just insert a disk into the drive and have it show up in winUAE, under workbench or otherwise.
It's basically a disk copier. You can copy a real disk to an image file, and vice-versa.
I had hoped I could do the same thing you are asking with mine, but it doesn't work like that.
It does work with standard 1.44m drives, and will work with most NDOS disks.
