Weakbits apparently works fine. Turrican II works, and it has weakbit protection on track 0, head 1.
I don't have any originals with no flux areas. I know that Ivanhoe has this protection, but when I bought a disk from a seller in the U.K. I learned (from looking at the disk) that it is a copy that has a parameter run on it. The disk is identical, but the protection check always passes no matter what is on the protected track. I have noticed a LOT of disks coming from the U.K that have silkscreened labels. Some of the original disks were this way, but most were not - and these "originals" have silkscreened labels and have NO copy protection on them - but contain the normal AmigaDOS data in the exact same spot - just a protection bypass. These are copied on a commercial duplicator though, perhaps one of the little single disk units.
