I had no problems copying some Apple 6.x system disks when I first designed SuperCard Pro, so there is nothing inheritantly wrong with the low density GCR data. Having a single bad sector on each track makes sense because that would mean the write splice ended up somewhere within a valid sector instead of the track gap. I know that a8rawconv can read/decode low density Mac disks as well as Apple II disks.
