No. It is even worse. Due to head stepping speed limitiations, the transfer
speed is approximately 15 kB/s

A while ago, I wrote a new loader for fastcopy, which detects the presence
of more (hard)disk interfaces and gives you the choice to enter the correct
interface. You can find this new loader enclosed with this mail. This new
loader is for fastcopy version 3.0
