Ok, thank you again.
Now I'll wait for my kryoflux and let's see what happens.

I received my kryoflux and I started to test it with some disks.
It seems it's working good, the only "strange" think it's that I often see "orange" sectors with the "additional information on header" warning, but probably it's normal.

Just one question: it's there any sequence to follow when turning off the kryoflux? In the quick start guide there is a precise sequence about the turning on sequence, but no mention about the turning off.

Yes, those orange header warnings are normal for user data disks. They are important only if you are archiving an original professionally master software disk, as that indicates a user may have written to the disk, altering the contents.

I'd expect the proper power down sequence to be the reverse of power up. Just don't disconnect the ribbon cable or any added grounding and you should be fine. (I just power my drives from my PC's power supply so it all gets turns on/shut off at the same time).

I dumped about a half of my disks, kryoflux is working very well.
I have only a small doubt: i noticed that the generated .img images have a size of 720kb, but i use 360kb disks. Is it normal? I selected "MFM sector image" as suggested.

Looks as If you are decoding to 80 Tracks instead of 40....
