Here is mine:
Works fine in WinUAE just not on a Real Amiga 1200. I have a second adapter that I am thinking about trying this evening.
BTW, I tried IDE0 And UAE and both work fine in WinUAE.
I did find that one of my Compact Flash Readers could not read my 4 Gig Card due to the Compact Flash card being Hi Speed or something. Reads my older ones fine. I went to a place called MicroCenter and bought a ~$4 50-IN-1 Hi Speed card reader and it worked fine with that. I am wondering if that is your problem.
