Just one more question - what are the minimum requirements to add floppy drives to the KF compatibility list ? Do they have to be able to dump and restore certain heavily protected floppy disks in order to be called 'compatible'? Please give me a short info on this so I can add several drives to the...

Re: Best way to backup Amiga floppies

Thank you for this good explanation! So this is THE way to go: Use a DD drive for reading 3,5" DD disks and also for writing them back to 3,5" DD disks. Reading 3,5" DD disks with an HD drive could cause glitches to be detected as flux reversals. Writing back to 3,5" DD disks with an HD drive could ...

Re: Stream backup quality of 3,5" drives

Phew. That was hard photoshop work. There are many thoughts on this, but I'm no expert and maybe there is just nothing which can be derived from these scatterplots, but I'll give it a try: On track 8/0, the Mitsumi D359-T5 (DD!) seems to have the "tightest" scatterplot lines. On track 9/1, the ALPS ...

Re: Stream backup quality of 3,5" drives

Thanks for pointing this out! I've checked the graphs and there are some interesting(?) results which I'll post here. The later tracks (60ies and 70ies) look very similar on all drives. I've spotted some "interesting" patterns on track 24 (side 0), track 8 (side 0), track 9 (side 1) and also track 8...

Re: DTC sometimes just hangs after retrying an error on Amiga disk?

GUI is quite simple. You have an easy visual 'overview', you can see the scatterplot per track live and later with the mouse hovering over the tracks. Enable logging, set your desired output directory in options, calibrate the drive once, then just enter the base name of the game, select "multiple" ...

Re: DTC sometimes just hangs after retrying an error on Amiga disk?

KF GUI also uses the -l15 parameter if you switch on the logging option and to me it seems to be the most verbose output (I've even tried with 15, 31, 63).
