ah yes, for some reason, I had a hunch it was 4. So I can't have 3x 5.25" and 1x 3.5? Not a big deal, as I have the right cards. I just need to pull it out of my IIe.

I Could try the HD20, if I blow the port, I actually have 2 other IIgses I could use, though the other 2 are ROM 01s. I might just try it on one of those. I'll let you all know.
