Ok, so long story short, I have a box of floppies and a couple of them simply won't format anymore - not on my Windows 10 USB floppy nor on Windows 95 or 98. I've checked multiple physical drives and OSes. It's not a hardware issue. It's the floppy.

Does anyone have ready access to any software that might let me COMPLETELY low-level format a floppy to see if I can recover the physical disk for use? Like, the ability to write a brand new track 1 sector index marker, etc.

I am also not opposed to finding a really strong magnet to pass over the floppies to see if that will get them to format. Right now, the problem disks just keep getting kicked out as "failed to format floppy" within Windows 95/98. And Windows 10 doesn't even give me the option to low-level format - only quick format. I HAVE been unchecking that box in Win95, so that's not my issue.

Thanks in advance.

Note: I DO have working floppies in my little floppy disk box, but I'm trying to recover the ones that AREN'T working because we all know how hard it is to find floppies now.

What is that?

EDIT: Nevermind - web searches are my friend. Looks like a Linux format program. The only Linux system I have running is my home media server and that computer doesn't have a floppy drive attached to it at all.

The first google hit for me when I type fdformat & dos, second if I only look for fdformat.

edit, I guess this link has the compiled version at the bottom of the page.

http://toastytech.com/files/nformat.html Nformat is the other one, both of them also have the ability to create "strange" formats like Microsoft DMF 21 sector, or to create optimized formats which skew on step so you don't lose a full rotation, typical optimized skew format is 3 for step and 0 or 1 on head switch

There's nothing better than "format a: /u" under DOS.
All you can do is to run format several times - sometimes the media is slightly dirty, and it cleans itself while revolving.
I've seen many times when the first run of format resulted in some bad sectors, the second in fewer bad sectors, and another in no bad sectors at all.

But if this fails, then the hardware is bad, and no software can help.
