I see much more than what I would I would guess is the sector count. Wouldn't these write splicing fluxes distribute quite evenly in terms of length, creating a noise of weird fluxes? In this case there are quite some fluxes centered around 84. If this would be a result of write splicing I would think the same would happen on the RX02 disk. I cannot see any of these long type fluxes there. How can that be explained? /Mattis > Jon >
