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).

Re: Best way to backup Amiga floppies

Even back in the old days I had the feeling that HD disks are more likely to generate errors when written & read with DD floppy drives (on real Amigas) than DD disks (unless you had an A4000 with HD floppy drive). People are still selling(!) DD disks all over the place, but I'd better not buy nor us...

Re: Best way to backup Amiga floppies

Can 3,5" DD drives also write back KF stream tracks onto DD disks no matter whether they've been imaged with an HD or DD drive?

Stream backup quality of 3,5" drives

Is it in any way possible to determine which floppy drives are providing the best streaming backup quality from Amiga DD disks? I have several drives and would like to find out which are "good ones" for backup and also for successful restore (probably later). HD: ALPS DF 354H1 68F (max=83) Mitsumi D...

Re: Best way to backup Amiga floppies

Backup and restore with Alps DF354 H168F (similar to another ALPS drive, only with silver front panel) or Mitsumi D359M3 - both are IBM HD floppy drives. For restoring the images I used mint Sony DD floppies. And everything on 3,5" of course. ;)

Re: Best way to backup Amiga floppies

Thank you for the good explanation. In the meantime I've dumped several protected Amiga NDOS disks with different floppy drives and only recently I started to write stream files back to disk to see whether they'd run on a real Amiga - and they did. :) I used the following command: dtc -fGemX/track -...

Re: Problem with stream format on OSX

Great. I'll then give that one a try as well. :)
