Re: Need advice on how to recover 5.25" floppy

Ok, it seems i found the cause of the problem.
It seems that one of the two drives i use is defective and can't write disk. I connected kryoflux to the other drive and it writes disks correctly.
Thank for your help

Re: Need advice on how to recover 5.25" floppy

There is a way to create raw stream files from standard nonprotected DOS disk .img imagefiles using HxCFloppy software and then writing from those using KryoFlux.

Re: Need advice on how to recover 5.25" floppy

Is there some way to write on a ibm dos floppy?
I tried the "WildeWutz" GUI but it says "supported file types: ADF, G64, IPF & STREAM", is there some way to write a .img file?

Re: Need advice on how to recover 5.25" floppy

Image format is almost the same as d64! Both is basically a sector-for-sector copy of a disk... 683 sectors of 256 byte resulting in 174848 byte which is the length of a d64 file. 2880 sectors of 512 byte resulting in 1474 560 byte which is the lengt of a standard img file (1,44 MBdisk) There are n...

Re: Need advice on how to recover 5.25" floppy

Yes, i also tried to extract the graphs and all the side1 tracks seem unformatted:

It's all more clear now, thank for your help.

Re: Need advice on how to recover 5.25" floppy

ok, i got this: https://pastebin.com/tQVyXrkx
If seems that all side1 it's not formatted, so probably it's not a "flippy" disk and it's written only on one side, right?
This is the filtered view for the side1 tracks: https://pastebin.com/D8vkvwNi
