Weird problem writing 'weak flux' pattern
I can do that but note my problem is not with the weak bits themselves. I am generating a nice 200ms-long track which contains a sync (44894489) and a weak region, separated by a few hundred well-defined MFM bitcells (null padding). I therefore can't figure out why my sync pattern doesn't seem to make it to disk!

I agree that the generating of weak bits is itself tricky, I have a long pattern that works and a short pattern that works, on a couple of drives and various floppy disks. So that's okay for now as far as I'm concerned. It's just something somewhere is getting confused when I repeat the short pattern in a long weak region and I think track data is getting corrupted on its way to the disk.
