Addressing drive ID 0 (NOT PC drive A:)

[fplanque]

Using FluxEngine + Greaseweazle on MacOS:

I have the Greaseweasle working with gw with a DD disk drive from an Atari ST (drive ID 0 and straight non-twisted cable) and using a command like gw read --drive 0 --format=atarist.720 --retries=8 "test.st" does what it is supposed to do.

However, trying to use FluxEngine as a GUI, it can't get the drive to work:

• I can open the FluxEngine software, select drive:0, 3.5" 80 track, atarist, 720 kB and then click "Read Disk" -> It will display "Measuring drive rotational speed" and nothing more happens.
• If I select drive:1 the disk will spin for a few seconds then it stops and the UI is also frozen on "Measuring drive rotational speed".

Now, if I connect a PC 1.44" drive:

• I can read a PC disk (drive:0)
• I can read my Atari ST DD disk on this HD drive but with many many many more errors as on the DD drive (in gw). So using this drive is not a solution for me.

What am I missing?

does drive:0 actually mean "PC drive A on twisted cable"? How do I talk to a non-PC drive with drive ID set to 0 as it is on most non-PC computers?

With your Atari ST drive, ID 0, on straight cable, you must click on "Customize..." and add:

shugart_drive

With your PC drive (I suspect this time you connect it with a twisted cable, otherwise, it would be drive:1), you get many errors because your floppy disk is certainly a HD floppy disk where you missed to cover the right bottom hole with some tape. So the drive reads the DD disk with HD-corrected amplification.

"drive:0" actually means "PC drive A on twisted cable" when you don't mention "shugart_drive". When you mention it, "drive:0" becomes "drive 0 on flat cable"
