Yes, I spent some time working with Chris on a newer version of this device but we still couldn't pin point the problem, it's performance or reliability was always unstable (random corruption). Annoyed me too but since I didn't have that much information to transfer at the odd time I lived with it. I think he made the last version available online, I wouldn't be able to find it now anyway since my older Amigas are down south.
I think I only ever used it for USB stick transfers on my A4000.
