got even one more sector.

Good, checking with 'ndfs', I can both list and extract files from the image.
- 2020-02-04
- doing some regression testing. I've updated FluxEngine (both firmware and client software) to latest from git repository. Trying to read a 5.25 inch, ND format 17b floppy:
tingo@z30b:~/personal/projects/psoc/fluxengine/tmp$ ../fluxengine read ibm -s:d=1:t=0-76 --retries=0 -o 525-nd-f17b-211024-c01-xx-01d.image Error: unrecognised image filename extension
Ok, that's new. Well, let me try it another way then
tingo@z30b:~/personal/projects/psoc/fluxengine/tmp$ ../fluxengine read ibm -s:d=1:t=0-76 --retries=0 -o 525-nd-f17b-211024-c01-xx-01d.img Reading from: :d=1:s=0-1:t=0-76 Measuring rotational speed... 166ms [..] Autodetecting output geometry H.SS Tracks ---> 0. 0 ............................................................................. 0. 1 ............................................................................. 0. 2 ............................................................................. 0. 3 ............................................................................. 0. 4 ............................................................................. 0. 5 ............................................................................. 0. 6 ............................................................................. 0. 7 ............................................................................. 1. 0 ............................................................................. 1. 1 ............................................................................. 1. 2 ............................................................................. 1. 3 ............................................................................. 1. 4 ............................................................................. 1. 5 ............................................................................. 1. 6 ............................................................................. 1. 7 .............................................................................

looks good. Using the 'ndfs' tool, I verified that I can list and extract files from the image - it works.

A note on image naming. I use the '_rn' suffix on the name to note the revolutions parameters, so '_r2' is --revolutions=2, '_r6' is --revolutions=6 and so on. Torfinn (talk) 14:38, 12 July 2019 (UTC)

- the FluxEngine creator notified me that he had fixed some bugs, and that ND format 17b floppies was reading fine for him now, so I needed to test that as well. I updated the firmware and software to the latest from the Github repository (master branch), set up a 5.25 inch floppy drive and started testing. Torfinn (talk) 14:23, 12 July 2019 (UTC)

try with --revolutions=2 to see if it improves the reading

and ndfs can list it (I also tested extracting the files and that works too). I went on read more images, some were ok, and some were not. Torfinn (talk) 14:23, 12 July 2019 (UTC)
