The disk functions properly with DANIS506. Documentation mentions that for optimal performance a track must have a multiple of 8 (512B) sectors. With DFSee I could change the logical geometry to H=252 and S=120, but this seems to be ignored by DANIS506, although the BPM/BIOS column shows the changed value for H, but not for S! It would be nice to have the possibility to specify the geometry. Unfortunately without thie feature it is impossible to say if it would have any effect on the disk (write) performance!
