I try to make backups of disks of my Fairlight CMI IIx.

The Fairlight CMI IIx, use two qume track 242 or (YE-Data YD-174, Mitsubishi M2896-6, Nec FD-1165-FQ) ), floppy (8").

I make "blind dumps" of a one disks dump (17MB) with dtc -fname -i0 -i2 the file is here: http://jbemond.free.fr/SDIY/Fairlight/Fairlight_CMI_Blind-Dumps_i0_i2.zip

What is the best setting to make good images disk ?

Interesting one!

The disk can be dumped as:
DTC -fname.img -z0 -v360 -oe76 -i3 -l8 

It is unclear whether the disk is really double sided, or side 0 and side 1 are being used separately.

If it is separate sides:
DTC -fname.img -g2 -z0 -v360 -oe76 -i3 -l8 

The program you may want to use with the image (if not just backing up the disk) may require a specific track order; if you know what it is, it's fairly easy to add a parameter that creates an output image in that format.

In any case, as long as you keep the stream files, you can later generate the correct/expected image, so I suggest dumping the disks as:

DTC -fstreamname -i0 -i2 -fname.img -z0 -v360 -oe76 -i3 -l8 

or

DTC -fstreamname -i0 -i2 -z0 -v360 -oe76 -i3 -l8 
[no filename for the image]

If you don't want to create sector image(s).

Hope this helps.
