Thanks Gene,
I was wondering why, when it seemed too simple.
I will admit, whenever I am restoring a big box Amiga or a 1200/600. The first thing I do it ditch the old drive and go to AmigaKit and get a new (modded PC) floppy drive from them along with the other needed parts. On an A2000, they are off aesthetically, being white and a bit smaller than the original Chinon FB 354 Drives, but I got to the point where it was always pulling my hair out trying to install WorkBench and the floppy drive would get through 2 or 3 disks then fail. I don't even test them anymore, just replace. Amigakit has made them cheap enough that it's a no brainer for at least installing WorkBench. I of course, install "No Click" once WorkBench is up, the click was enough to drive people insane.
