try using FE (FluxEngine) to read a ND format 17b floppy which has read errors. First the normal way

try with --revolutions=10 then (even if it is going to be slow)

same as --revolutions=10 but quicker. now --revolutions=3 and --retries=5

got even one more sector.

another regression test - this time a 5.25 inch, ND format 0b floppy:
tingo@z30b:~/personal/projects/psoc/fluxengine/tmp$ ../fluxengine read ibm -s:d=1:s=0:t=0-76 --retries=0 -o 525-nd-f0b-nd-10005u.img

Good, checking with 'ndfs', I can both list and extract files from the image.

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

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

check the images I captured yesterday against the original images

these images are identical to the original images

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

tingo@kg-bsbox:~/personal/projects/psoc/fluxengine/tmp$ ../fluxengine read ibm -s :t=0-76 --retries=0 --revolutions=2 -o test-nd-525-210523g02-xx-01d_r2.image

a clean image. Nice!

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)

note - I did not test with the --hd (aka --high-density) option. I should test with that also. Torfinn (talk) 15:54, 12 July 2019 (UTC)
